Does anybody know of any good and free statistics libra开发者_开发知识库ries for .Net?

I am working on calculating T-Tests, which I have written a formula to calculate, although now I need a formula for the p-value, which is a little more complex, and not being a statistician, has me a little lost.

I suggest you look at the Math.NET project. It supports various distributions, but I don't know if it has t-tests and p-values.

Meta.Numerics has a lot of statistical functionality. It supports t-tests (one sample, two sample, paired), as well as Mann-Whitney and sign tests (non-parameteric alternatives to t-tests), and ANOVA (a t-test extended to more than two samples) and Kruskal-Wallis (a non-parameteric alternative to the ANOVA). And yes, it reports back a P-value with all tests.

Since version 4 the .NET libraries include the StatisticFormula class which provides T-Tests. This class is available in the namespaces System.Web.UI.DataVisualization.Charting and System.Windows.Forms.DataVisualization.Charting

Link to documentation and usage:

TTestResult result = Chart1.DataManipulator.Statistics.TTestUnEqualVariances(0.2, 0.05, "Series1", "Series2");
