You should look at CenterSpace Software's .NET stats package. We have binomial and poisson distributions, their CDF, and inverses (which can be a pain to accurately calculate.).
The Stats package offers high performance classes for:
- Clustering / K-Means clustering
- A wide variety of probability distributions and CDF's and inverse CDF's - including specifically binomial and poisson.
- Hypothesis Testing.
- Non-negative matrix factorization.
- Partial Least Squares.
- Regression (Linear, Anova, QR, SVD, and more).
- Principle Component Analysis.
