Inverse Probability Distributions?

Hi guys, And first of all congratulations for a stupendous looking package - I'm very excited about this project and I hope it keeps growing and gaining interest. I am starting to use Iridium for probability calculations, and need to get hold of the inverse function of the Beta distribution (ie what...

Inverse Gamma Function?

I just downloaded Iridium and am having trouble finding an inverse gamma function that I need for a project I'm working on. I'm not a stats guy so maybe it's there under another name and I jsut don't recognize it. I'm supposed to be using the inverse gamma to figure confidence intervals...

Iridium Statistics Accumulator: Better numerical stability

The algorithm on how the Mean, Variance and Sigma are incrementally computed in the statisics accumulator (MathNet.Numerics.Statistics.Accumulator) has been improved last week in Iridium revision 503 to provide better numeric stability when dealing with samples with a very large mean but only a small...

Student T-distribution

Hi folks, Im using instance of " MathNet.Numerics.Distributions. StudentsTDistribution" to generate TDIST() value which present in MS-Excel. The value is mismatching while executing. here i attach my code below. C#.net MathNet.Numerics.Distributions. StudentsTDistribution eg = new MathNet.Numerics...

Differences in Histogram methods

Hello, First, thank you for your great work on the library! It is great to finally see some open source math libraries for .NET. I am new to the library, and would like to know which method I should use to create a histogram. I do not understand if I should be using method OptimalDispersion, OptimalFreedom...

Re: Polynomial Extrapolation - How to...

Instead of an extrapolation I'd suggest to go with a least-aquares regression on one of these polynomials (3rd or maybe also 4th order). Interpolation/Extrapolation: You try to fit a curve exactly through all available data points. Least Squares Fitting: You try to fit a simpler curve close to a...

Re: Non linear multiple regression

Hi Lorenz, Although there are plans for various regression algorithms, and someone even offered to contribute some code in this area some time ago (years actually; I haven't heard from him since): Unfortunately not, at least not for the near future. I just don't have the time at the moment.....

New statistics accumulator

Hi I started building a vector accumulator based on MathNet.Numerics.Statistics.Accumulator, it's almost identical except that it operated on vectors (arrays of double in this case). Since the dimension of the vectors have to be enforced the interface has been changed slightly. The accumulator has...
