Description

I know it looks kind of arbitrary or unnecessary feature ,but I believe that

to provide such a feature as official is helpful to make people we couldn't reach so far have interest in Ruby.

(Actually only this feature is not enough to do that..)

By the way I still wonder whether naming method make sense.

Debating between ...

Math::pnorm   -> R language use this
Math::phi     -> Euler's totient function is more popular as phi,
Math::ncdf
Math::guesscdf
Math::cdf_of_norm,
Math::cdf_of_guess

Finally I come to the conclusion Math::normcdf is most proper length, meaning and has no other worries.
