3. ### Compare dummy variables in a regression analysis (not to baseline but among each other) ?

For my regression, I have a variable that has 5 levels (5 different government interventions). Since, I cannot assume the distances between the levels to be the same, I had to split the variable into 4 dummy variables. Now I get statistical information about the direct comparison between each of...
4. ### dummy regression - unequal sample sizes

Hello, I am conducting a linear regression analysis in SPSS with different variables: - scale, - 2-level nominal, - 5-level nominal (dummy) The sample sizes / frequencies for three of the five levels of my last dummy variables are under the recommended 15% (namely 12,5%, 5% and 5%). Can I...

I have a question regarding the PROCESS plugin for SPSS developed by Andrew F. Hayes. The analysis I'm running has one predictor, one outcome variable and 6 mediators (there are no interactions). For this analysis I want to control for 3 dummy variables that could have an influence on the...
7. ### Conditional change ordered logistic with different approach of same variable

LS, I am working with two-wave panel data looking at outcomes of retirement on self-rated health (5 point scale, very good to very bad)). It is questionable to interpret this variable as interval/ratio, therefore I use ordered logistic regression (ologit in STATA). The results show significant...
