Hi folks,
Sorry for troubling you guys. Hopefully somebody here can give me some advice on
the method of multinominal logistic model. Your help will be deeply
appreciated. Best, Yanbo
Question: What is the minimum number of observations required per category given
n independent variables? Is the rule the same in MLR as it is for a logistic
regression model (~20 observations per independent variable) for the entire MLR
(i.e., all of the nominal categories combined) or, since each nominal category
is a separate equation, does that imply that the number of observations per
category be at least 20*(the number of independent variables).
