Hi there,
I am running OLS regression with different fixed effects and, to deal with these, I am using the felm package. My regression includes also some categorical and dummy variables which I specify as "factor(x)" in the equation. When looking at the output, I have the estimated coefficients for all values of the categorical variables. When using lm, only the coefficient for value == 1 (or 0) is estimated, not both. I'm confused about how to interpret these coefficients. Is there something wrong in including categorical variables in felm estimation?
Thanks.
