Alex Herbert updated STATISTICS-97:
-----------------------------------
Description:
The TTest and OneWayAnova compute the variance of input data. This computes a
variance of NaN if any value in the input array is NaN or Infinite.
The TTest also accepts a mean of NaN when the mean, variance and sample size
are known.
These conditions invalidates the test as the test statistic is NaN.
Issue identified by a security scan.
