    Description

      This ticket will add two Stream Evaluators:

      a) regress: Performs simple regression on two columns of numbers and returns a regression result.

      b) predict: returns a prediction for an independent variable based on a regression result.

      syntax:

      a = regress(colA, colB)
b = predict(a, 50)

      The implementations will be provided by Apache Commons Math
