*n*= 55. Now, assume that the predictor has three categories, and that I obtain 55 necessary responses. What does it mean for the regression analysis if the number of observations in each category is distributed as something like 5, 10, and 40? That is, 5 observations in category #1, 10 in cat #2 and 40 in cat #3. Or consider a binary predictor variable with 5 in cat #1 and 50 in cat #2? I have achieved the minimum sample size projection, but do I have enuf data across the categories? Is there a minimum number per category that I should be looking for?

Thanx!
