Commented Unassigned: Hypergeometric breaks on large values [5729]
First of all, the documentation is not very clear. The input arguments are not explained so it took me sometime to find out how it is parameterized. CumulativeDistribution calculates P(X < x) not...

View ArticleEdited Feature: Modulo operator on matrix and vector [5662]
Hi - Is there a modulus operator on a matrix? More specifically, I'm creating a matrix: var matrixA = new DenseMatrix(new[,] { { 5.0, 8.0 }, { 17.0, 3.0 } });and I would like to perform the following...

Hi Christoph! First, thank you for your kind response. I've came to this same conclusion when I realized that the Matrix type uses two-dimensional arrays (Complex[,]), which are not supported by .Net...

I've just added a LogNormal.Estimate function for exactly that (maximum likelihood) that will be included in the next release. In the meantime, simply take the natural logarithm of each sample and then...

Hello, I've been developing a massive multivariable parallel random number generator. The idea is to feed it with a correlation matrix and use it as a seed to create random correlated numbers. The math...

Hi Rafael, It seems to me MatrixNormal (wikipedia) is not exactly but quite close to what you describe. It is parametrized by a mean matrix and two covariance matrices for rows and columns. Sampling is...

Thanks Christoph! I was giving a look at the documentation, but I didn't fully understand how to use it. There you say:The distribution is parameterized by a mean matrix (M), a covariance matrix for...

I checked them as of today, and they do not appear to be strong named. Any way we could get this fixed sometime soon please?

Indeed, I must have had uploaded the unsigned package instead of the signed one by mistake (they were both the same). Fixed.

Hi, Do you have the same method for a normal distribution (like "normfit" MatLab method) to get mu and sigma ? By the way, where is the extention for MeanVariance ? Thanks a lot !
View ArticleNew Post: Estimate mu and sigma
Yes, I had added the equivalent to the Normal distribution as well, in the same commit. MeanVariance is new in the Statistics.Statistics class, but you can just use Mean and Variance separately to the...
