[math] protected methods in OLS regression class???

[michael.brzustow...@gmail.com]

Hi,

Is there reason that OLSMultipleLinearRegression.calculateBeta()
and OLSMultipleLinearRegression.calculateBetaVariance() are protected and
not public?

Is this used for testing purposes ... or just an oversight ... or am I just
using the class wrong?

Thanx!
