NORMAL=BLOM  normal scores from the ranks. The resulting variables appear normally distributed.nis the number of observations that have nonmissing values of the ranking variable for TIES=LOW, TIES=MEAN, and TIES=HIGH. For TIES=DENSE,nis the number of observations that have unique nonmissing values. The formulas are as follows:
BLOMyi=-1((ri-3/8)/(n+1/4))

-1is the inverse cumulative normal (PROBIT) function,riis the rank of theith observation, andnis the number of nonmissing observations for the ranking variable， yi is the rank number

请问，这里的inverse cumulative normal (PROBIT) function和inverse cumulative normal function有区别吗？
后者在STATA中可以用invnormal(n)来实现，前者呢？
