Probability Distributions in NMath Stats

Posted on March 2, 2010August 31, 2020 by Paul Shirkey

Probability distributions are central to many applications in statistical analysis. The NMath Stats library offers a large set of probability distributions, covering most domains of application, all with an easy to use common interface. Each distribution class uses numerically stable accurate algorithms to compute both the probability distribution and the cumulative distribution. In this post we...

Using Excel with NMath

Posted on February 15, 2010March 1, 2016 by Paul Shirkey

We've had several customers ask about porting their Excel model to a .NET language in order to leverage the performance and functionality of NMath or NMath Stats. NMath does have good crossover functionality with Excel making this porting job easier. It is also possible to accelerate your Excel models by calling the NMath .NET assemblies directly from a VBA macro in Excel . This post provides some...

Forward Scaling Computing

Posted on January 28, 2010March 2, 2016 by Paul Shirkey

Forward Scaling for Multicore Performance The era of sequential, single-threaded software development deployed to a uniprocessor machine is rapidly fading into history. Nearly all computers sold today have at least two, if not four cores - and will have eight in the near future. Intel announced last month the successful production and testing of a new 48-core research processor which will be ma...

Power Spectral Density with NMath

Posted on January 13, 2010June 2, 2020 by Paul Shirkey

Application Note Computing the Power Spectrum in C# We've had several customers ask about computing the PSD in C# with NMath, so I thought it was time for a post on the subject. The power spectral density provides an estimate of the power present within each slice of spectrum, and is presented as graph of the signal power versus frequency. It's a common signal processing calculation across many fi...
