I'm running a multiple regression with 4 predictors, and when I examined the Standardized residuals.

a Graph is below.

I'm just curious what this means for my regression. Can I not interpret the Beta values the same?

Do I need to fix this problem?

What I am interested in is showing the effects of each of my predictors on my DV.

what sorts of biases might this lead too and do I need to fix this?

Thank you.
