The graphical user interface has two views which can be toggled by clicking on one of the two tabs in the bottom left of the SPSS Statistics window. The 'Data View' shows a spreadsheet view of the cases (rows) and variables (columns). Unlike spreadsheets, the data cells can only contain numbers or text, and formulas cannot be stored in these cells. The 'Variable View' displays the metadata dictionary where each row represents a variable and shows the variable name, variable label, value label(s), print width, measurement type, and a variety of other characteristics. Cells in both views can be manually edited, defining the file structure and allowing data entry without using command syntax. This may be sufficient for small datasets. Larger datasets such as statistical surveys are more often created in data entry software, or entered during computer-assisted personal interviewing, by scanning and using optical character recognition and optical mark recognition software, or by direct capture from online questionnaires. These datasets are then read into SPSS.

The second thing is to select All in the Function group on the right of the dialog. This will allow you to select $Casenum in the Functions and Special Variables box. The $Casenum variable is just the number of cases read up to and including the current case. So, for example, the function will return the number 3 for the third case (normally, but not always, the third row in the Data View), the number 4 for the fourth case, and so on. This will generate a set of unique integers that can function as ID numbers.
The main advantage of this software complex is that it is the most important achievements in the field of computerized data analysis.It is the widest coverage of existing statistical methods, which successfully combines with a huge number of convenient means of visualizing the results of processing. IBM SPSSS Updated Version registered contains the minimum necessary amount of information on the theory of statistical analysis. The focus is on the features of the use of the individual method. The opportunity is that these methods provide the clarification of the result of applying these methods. As well as, it provides helps to describe the presentation capabilities of SPSS which enhances the scope of functions provided by other business programs like Excel and more.
In SPSS, date-time variables are treated as a special type of numeric variable. All SPSS date-time variables, regardless of whether they're a date or a duration, are stored in SPSS as the number of seconds since October 14, 1582. This means that "under the hood", date-time variables are actually integers! This might not seem important, but it's what makes it possible to do "date arithmetic", such as computing the elapsed time between two dates, or adding and subtracting units of time from a date.
Fortunately, you as the user do not normally need to interact with the underlying integers, and you can type in data values for date and time variables using normal date-time conventions. However, dates and times can be written using a number of different conventions, so we need a way to tell SPSS how to read and parse our date strings. That's where the concept of date formats comes in.
In the "general form" column, the name of the format appears first, followed by the letter w (or w.d). The letter w denotes the number of "columns" (typically the number of characters in the input string), and the letter d represents the number of decimal places, if present. You will replace these with the appropriate number to use for the width of the date.
Just as with date formats, the "general form" of the format name contains w (or w.d). The letter w denotes the number of "columns" (typically the number of characters in the input string), and the letter d represents the number of decimal places, if present. You will replace these with the appropriate number to use for the width of the date.
BDate1: The right half of the dialog box is where we will specify which variables to use, and how to set up the calculation. In the Date1 field, select the variable date_of_enrollment and in the minus Date 2 field, select the variable bday. This specifies that SPSS should calculate date_of_enrollment minus bday, which will yield the number of years between when the person was born and when they enrolled in college (i.e., their age at college enrollment).
DResult Treatment: Specify how to treat the values of the variable that will be calculated. You can choose to truncate to integer, round to integer, or retain fractional part.Truncate to integer means dropping the fractional part (e.g., 1.3 would become 1, and 1.6 would become 1).Round to integer bumps the number to the nearest integer (e.g., 1.3 would round to 1, but 1.6 would round to 2).Retain fractional part means that the fraction will remain (e.g., 1.6 remains 1.6).In this example, fractions will be retained so that the values for the new variable reflect the individual's exact age (in years) when they enrolled in college.
A new 48-core system node option (#EPBD) is added to the existing32-core system node for the Power E880 (9119-MHE) server. One, two,three, or four of the 4.02 GHz 48-core system nodes provides a48-core, 96-core, 144-core, or 192-core server. All the system nodesin the server must be the same gigahertz and feature number.
No-charge elastic processor and memory days are available with theinitial system order or with a same-serial-number model upgrade. Youcan receive 15 processor days and 240 GB days for every active andinactive processor core initially. Order this by using theappropriate quantity of features EPJ5 and EMJ9.
Like the 32-core Power E880 server, same-serial-number upgradesfrom the Power 780 server are available to the 48-core Power E880server. Additional feature conversions to the 48-core processor andactivation features are announced for this purpose.
The number of PCIe adapters supported in the Power E870/E880 systemnode is more than doubled. This provides additional configurationflexibility. The following additional adapters, which had beenpreviously announced on other servers, are now supported in the systemnode:
With additional PCIe Gen3 I/O drawers, the maximum number of PCIeadapters is increased. Associated with the increase in the number ofSAS adapters in an increase to the EXP24S HDD/SSD drawer (#5887). TheE870 now supports up to 3,072 drives with a new maximum of 128 EXP24Sdrawers. The E880 now supports up to 4,032 drives with a new maximumof 168 EXP24S drawers. The maximum of 16 EXP24S drawers per PCIe Gen3I/O drawer due to cabling considerations remains unchanged.
The PCIe3 4-port 10GbE Adapter doubles the number of 10GbE portsper adapter, saving PCIe slots on POWER8 servers. The adapter issupported in full-high slots such as the PCIe Gen3 I/O drawer and the4U scale-out system units and in the Power E870/E880 system nodeslots. It does not fit in the 2U scale-out server low-profile slots.In addition to Ethernet NIC support, it also provides SR-IOV NICsupport, which can allow further virtualization and slot savings.
As part of the IBM commitment to delivering the most flexible andresilient Power high-end systems, all initial shipments of Power E880systems come with a specific number of no-charge elastic processor andmemory days. The number of days depends on the configuration of thesystem. For every new Power E880, 15 elastic CoD processor days forevery processor core (inactive or active) installed on the system and240 GB of elastic CoD memory days for every processor core (inactiveor active) are included. These elastic CoD processor and memory daysmust be used in accordance with the temporary capacity on demand termsand conditions. Also available are 90-day temporary elastic CoDprocessor and memory enablement features. These features enable asystem to temporarily activate all inactive processor and memory CoDresources for a maximum of 90 days before you must order anothertemporary elastic enablement feature number.
It is highly recommended that the Power E880 be ordered with an IBM42U enterprise rack (7014-T42 or #0553). An initial system order isplaced in a 7014-T42 rack. A same serial-number model upgrade MES isplaced in a feature 0553 rack. This is done to ease and speed clientinstallation, provide a more complete and higher quality environmentfor IBM Manufacturing system assembly and testing, and provide a morecomplete shipping package.
With the 2 meter 7014-T42 or feature 0553, a rear rack extension of8 inches or 20.3 cm (#ERG0) provides space to hold cables on the sideof the rack and keep the center area clear for cooling and serviceaccess. Including this extension is very, very strongly recommendedwhere large numbers of thicker I/O cables are present or may be addedin the future. The definition of a "large number" depends on the typeof I/O cables used. Probably around 64 short-length SAS cables perside of a rack or around 50 longer-length (thicker) SAS cables perside of a rack is a good rule of thumb. Generally, other I/O cablesare thinner and easier to fit in the sides of the rack and the numberof cables can be higher. SAS cables are most commonly found withmultiple EXP24S SAS drawers (#5887) driven by multiple PCIe SASadapters. For this reason, it can be a very good practice to keepmultiple EXP24S drawers in the same rack as the PCIe Gen3 I/O draweror in a separate rack close to the PCIe Gen3 I/O drawer, usingshorter, thinner SAS cables. The feature ERG0 extension can be goodto use even with a smaller numbers of cables as it enhances the easeof cable management with the extra space it provides.
For clients loading the IBM i operating system, the four-digitnumeric QPRCFEAT value used on the 9119-MME or 9119-MHE is the same asthe four-digit numeric feature number for the processors used in thesystem. For example, if the processor feature number in a system isEPBA, the QPRCFEAT value for the system would be EPBA. 2ff7e9595c
