I'm desperatelly looking for help regarding an regression analysis I'd like to conduct. Apparently the residuals/error terms of the dependent variable are not normally distributed. A shapiro wilk test has confirmed this. However, different visualizations suggest that the distribution is not that far away from a normal distribution. I have already tried to transform the data of the Y varibale, but about half the data has negative values, which eliminates logarithms and square roots. The transformation 1/y stressed the problem even more. The data sample contains about 100 observtions.

What should I do?

Thank you so much!
