"Well don't put them into the model as dummies - put them in as a categorical so you have control. " What is the difference between a dummy variable and a categorical variable?

3 variables , each has prespecified odds ratio which are significant and in a predetermined confidence interval

for example after multivariate logistic regression analysis I find A variables odds 1.4 (1.1-16) , B variables 1.6 ( 1.23-1.40) and C variable 2.3 ( 1.4-3.3)

now I want 120 A,B, C variables with a prespecified mean, SD, how can I produce this data
