*year*) that I was supposed to include in my regression model as a fixed effect. I just found out that it is heavily right-skewed(most observation in the last 4 years of sample period of 20 years) and ruins my model fit. Every other control variable, that is signficant when not including

*year,*loses it´s significants if I include

*year*.

I was told I can not include the

*year*variable in the regression if I give a good explanation for why I excluded it. Am I right, that the inclusion of

*year*would overstate the significance of observations in the later years and "overfit" the model?
