Lesson 2: Examining Your OutputWe just ran crosstabs to test a hypothesis with two variables one nominal (SEX-independent variable) and one ordinal (AFFRMACT-dependent variable). The one-way ANCOVA (analysis of covariance) can be thought of as an extension of the one-way ANOVA to incorporate a covariate.Like the one-way ANOVA, the one-way ANCOVA is used to determine whether there are any significant differences between two or more independent (unrelated) groups on a dependent variable. As you can see the categories of the independent variable are found across the top in the columns and the dependent variable information is found down the side forming the rows. In SPSS, recoding categorical string variables to numeric codes and converting blank strings to missing values can be done automatically using Automatic Recode. In addition to knowing the “center” of your data, you will also want to know its dispersion (how far it is spread out around your “center”). When reading data containing dates or using certain date-time functions, we need to tell SPSS which date format to use, so that it knows how to correctly parse the components of the input string. These different results in performance and in estimates encouraged us to investigate the similarities and discrepancy between the GEE methods in R (version 3.0.2), SAS (version 9.4), and SPSS (version 22.0.0) for longitudinal ordinal data using simulation studies.

SPSS Base (Manual: SPSS Base 11.0 for Windows User’s Guide): This provides methods for data description, simple inference for con-tinuous and categorical data and linear regression and is, therefore, sufficient to carry out the analyses in Chapters 2, 3, and 4. Published with written permission from SPSS Statistics, IBM Corporation. “Gender” can be “Male” or “Female” but do not give “M” or “F”. That change causes the balance to shift Stepwise linear regression is a method of regressing multiple variables while simultaneously removing those that aren't important. Ordinal shift analysis uses ordinal logistic regression to estimate a common odds ratio for all possible outcome category thresholds.
