I am trying to recreate what my predecessor has done, with the only knowledge being he used "regression."
I'm predicting my dependent variable based on the day of the week, but also on two other quantitative variables. I initially intended to use indicator variables for the week day, but then remembered that I will not be able to get a coefficient for each of the seven days, though my predecessor was able to somehow get a model with coefficients for all of Sunday-Saturday.
Is there another way I can tackle this problem, or is this method the best way? Is there a method I can use to get separate coefficients for each day of the week?
