Convert first letter of each word to uppercase (v.2) 1 This syntax takes address line, parse it into separate word then capitalizes first letter of Coutts, J., Hayes, A. Concatenate All Values Into Constant Getting constant string, unifying all values of another string variable. Transfer the Lg10 function into the Numeric Expression: box by pressing the button.Concatenate/modify string variables. To do this, click 'All' in the Function group: box, then scroll down in the Functions and Special Variables: box and click 'Lg10' to select it. You need to first select the function you would like to use.

Initially, variables have scary-looking names like 'VAR00001'. In which save means save z-scores as.Coding variables in SPSS: To set up these variables, open SPSS and click on the 'variable view' tab in the bottom left corner of the screen. Numerous additional options are available, including options for controlling for covariates and saving bootstrap estimates of effects for further analysis.SPSS users can easily add z-scores to their data by using a DESCRIPTIVES command as in descriptives test1 test2/save. MEDYAD also allows for the specification of an X or Y that measures a property of the dyad rather than of the individual member of the dyad. MEDYAD allows up to twelve mediators (up to six measured on each member of the dyad, or twelve if each mediator measures an aspect of the relationship or a single member of the dyad) and can conduct contrasts between indirect effects within and between dyads and between and within mediators.

Use omega rather than Cronbach's alpha for estimating reliability. SPSS date formats as applied to an example date/time of Thursday, January 31, 2013.Hayes, A. ( SPSS will only accept single-word variableThe actual date formats that you will use in your SPSS syntax are as follows.

The OMEGA macro also generates all possible subscales of at least three items from an additive scale containing k items. Omega is an easy-to use macro for SPSS and SAS that calculates McDonald's omega without relying on the estimation of factor loadings or error variances using CFA. Hindering its more widespread adoption is the fact that the computation of omega heretofore has required the estimation of item factor loadings and error variances in a confirmatory factor analysis (CFA). Yet methodologists have warned that a is not an optimal measure of reliability relative to its more general form, McDonald's omega. Cronbach's alpha is the most widely-used measure of reliability when estimating the amount of random measurement error that exists in a sum score or average generated by a multi-item measurement scale.

Two condition within-participant statistical mediation analysis: A path-analytic framework. Most of the features available for omega are also available for Cronbach's alpha, which the OMEGA macro can also generate.(Note: The archive also contains the "blirt" data files mentioned in the paper)( MEdiation and MOderation in REpeated-measures designs)Montoya, A. It also generates summary statistics making it easy to find the most psychometrically appealing brief form of a longer measurement instrument.

In addition to the usual regression program output, it has options for heteroscedasticity-consistent inference (using either the HC0, HC1, HC2, HC3, or HC4 variance-covariance matrix), automatic coding of a multicategorical categorical regressor, options for estimating and probing interactions involving a multicategorical regressor, all subsets regression, spline regression, crossvalidation indices for the multiple correlation, an implementation of a limited form of dominance analysis, contrasts between regression coefficients, and a few other features. Available for SPSS and SAS, RLM is a supplement to SAS and SPSS's regression modules. It can be downloaded from the book's web page and is documented in Appendix A of the book. New York: The Guilford Press The RLM macro was released with the publication of Regression Analysis and Linear Models in the summer of 2016.
