Generalized extreme value distribution Parameter Estimation

Hello,

I'm trying to calculate the parameters needed to fit unknown data to the GEV distribution; but I'm having some trouble doing so.

According to wikipeida: https://en.wikipedia.org/wiki/Generalized_extreme_value_distribution

I can calculate this using the equations shown on the right. I can get the mean, mode, or Varience of the data I have and use it to solve for k (the shape parameter).

I can't seem to get it right.

How would I go about doing this?

Thank you
