A quick answer is that the prob>z is testing the null hypothesis of
normality.  If p<0.05 the argument is that the statistic can not accept
the null hypothesis of normality.  So in your case as  Jesus point's out
the results below indicate unable to reject the null hypothesis -
suggestive that the relationship is normal

Hi,
Does anyone know how to interpret the result of swilk function. Like my
result is
  swilk ag, lnnormal

          Shapiro-Wilk W test for 3-parameter lognormal data
     Variable |    Obs        W          V          z     Prob>z
-------------+-------------------------------------------------
           ag |   1199    0.79999    148.830     -1.088  0.86173


Shall I reject or accept the null hypothesis?
Thanks
Jiehua
