First of all, Thanks for this good library.
I'm using two Regressions of BivariateSample such as Linear and polynomial.
I can't find where i find rsquare value in FitResult class.
In case of Linear, I use BivariateSample.CorrelationCoefficient * BivariateSample.CorrelationCoefficient.
In case of Polynomial, Any other ways of get rsquare value?

You can get r for a BivariateSample using PearsonRTest().Statistic. Its square is the r^2 for a linear fit, which you can also get by summing the squares of the residuals dividing by n2. The r^2 for other fits is defined by analogy and can be computed
analogously: sum the squares of the residuals and divide by n minus the number of fit parameters.
In future releases, we will make it easier to get to this information.
