Dear Stata Users

Sorry for such a novice-level question.

I ran an ols regression with 15 estimators and 14831 observations. In
this process, 437 missing values were generated. Then I tested
normality of the residual using sktest and it returned following
output.

Variable |  Pr(Skewness)   Pr(Kurtosis)  adj chi2(2)    Prob>chi2
---------------------------------------------------------------------------------------------
    ewhe |        0.000             0.000               .                .

whereas, sktest with noadjust option returned the following output

Variable |  Pr(Skewness)   Pr(Kurtosis)  adj chi2(2)    Prob>chi2
---------------------------------------------------------------------------------------------
    ewhe |        0.000             0.000           3693.33       0.0000


Where're the statistics of chi2 in the first instance? Does it mean
that sktest (without no adjust) is sensitive to the missing values?
Can I use jb test with 14000+ observations? If not than what other
"quantitative" tests are available?
(Or am I misinterpreting something?)

Thank you very much in advance
