Use USTATS or TABLES with STATS=USTATS to compute the kurtosis of a
variable.
To test departures from normality: for N greater than 1000,
refer the critical ratio of the kurtosis
measure to a table of the
unit normal curve; for N between 200 and 1000, refer the
kurtosis measure to a table
for testing kurtosis; for N less
than
200, use Geary's criterion.
