Select Analyze->Descriptive Statistics->Explore from the menus, click the Plots button and check "Normality plots with tests". If the population mean and standard deviation are not available, use the EXAMINE procedure. Solution: If possible, use syntax to specify the population mean and standard deviation for NPAR TESTS. Problem: If you run the older Nonparametric tests procedure (NPAR TESTS), request a one-sample K-S test, and use the sample data to calculate the mean and standard deviation, the significance test for the K-S statistic is not calculated with the Lilliefors correction.
That will run an EXAMINE command and K-S test with Lilliefors correction. Solution: If possible, supply a custom (population) mean and standard deviation when requesting one-sample K-S tests from NPTESTS. Problem: If you run the newer Nonparametric tests procedure (NPTESTS), request a one-sample K-S test, and use the sample data to calculate the mean and standard deviation, the significance test for the K-S statistic is not calculated with the Lilliefors correction. If you encounter this problem while following the steps in the "Using simulation to model treatment costs for diabetes" Case Study, copy diabetes_costs.xml from the Samples subdirectory to a writeable location. If that folder does not have write permission, you can correct the problem by moving the model file to a location that does have write permission. Solution: Check the permissions of the folder in which the model file is located. Problem: When you use Simulation Builder to select a model file, the file may fail to open and the application may become unresponsive. Solution: When you enter correlations into the simulation plan, be sure to select the "Do not recalculate correlations when fitting" radio button before saving the plan. Problem: Simulation may fail to save user-entered correlations in the simulation plan (.splan). Solution: Use the English locale when you need to enter numbers in the Simulation user interface. Problem: In the Simulation dialog boxes, commas do not work as expected when in a comma-delimited locale. Solution: To avoid the problem, click the Browse button before you enter the name of the file. Problem: If you use the Map Conversion Utility to create a data set as an SPSS Statistics data file (.sav), the file can get saved as comma-separated (.csv) instead.
Solution: Use the Teradata ODBC driver available from. We have reported the problem to Data Direct, the developer of the driver. Problem: When using the Database Wizard with the Data Direct Teradata driver, you might not be able to complete all the steps in the Wizard.
Solution: Do not change the file attributes of encrypted files.
Problem: If you encrypt a data or output file with a password and then change that file's attributes to read-only, you may have a problem opening that file in IBM SPSS Statistics. Īt time of publication, the following issues were known.
