I am using logistic regression to predict electricity spike prices (price that exceeds a certain threshold).
I directly use the following variables as my independent variables together:
(a) demand/load - a continuous IV
(b) is a binary IV
(c) days of the week
(d) months of the year.
I used the reference category for (c) and (d) and end up
tue for the reference. How do I interpret the results using marginal effects for all my predictors?
I am using Stata 9.
