> 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.
