If you have an admin right, to install the spd file you can double-click the file. Alternatively, you have to install it via: Extensions --> Utilities --> Install Custom Dialog

This version works fine in SPSS ver 26.

Running the macro without installation

You can run the macro without having it installed on your machine.

You have to download this file: ModLR.sps and RunModLR from my github page here.

Open ModLR.sps on your SPSS (it will be opened in a syntax file), run the syntax file (highlight all the lines, run the selection button, i.e., the green button).

Next, open and run Runthemacro.sps, change the model information according to your model specifications, and run the file.

ModLR is a SPSS macro to analyse moderated regression model that includes a number of covariates, a predictor and moderator variable. The program is written in spd extension format, which can be installed via custom dialog in SPSS.

ModLR is capable of performing a moderated regression analysis with a categorical moderator (0, 1 dummy) in which case the lower and upper boundaries of the Johnson-Neyman region of insignificance will be reported. It can also be used to analyze 2x2 ANOVA between-subject design with covariates provided that the categorical variables are coded as 0 and 1.

If you click 'Option', ModLR contains the multimodel inference approach for checking potential spurious moderation.
