Comparing Distributions

[cel]

If I have an observed variable X and a fitted value of X (X_fit) from some regression, is there a way that I can check if X_fit comes from the same "distribution" of X.

I've seen equality tests for mean, median & volatility and some discussion of quantile comparisons, but I stll thought to clarify what's the preferred way that E-views would allow you to assess this.

Thanks!
