Compare LO algorithm with Gnumeric algorithm
Calc toggles the variances, so that always the test statistic F is larger as 1.
It assumes, that then the right tail probability will be smaller than 0.5. That
is true in cases where the amount of data in the two series are large and
nearly equal. But you can construct cases, where this assumption is wrong.
The example file contains the correct algorithm in steps, so that it can be
easily transfered to the code. The case distinction to get F>1 has to be
removed in the code.
