Linq extensions to calculate basic statistics.

Extension methods to compute basic statistics modeled after Enumerable.Average. Stats include:

- Covariance

- Median

- Mode

- Pearson's Correlation Coefficient

- Range

- Standard Deviation (sample and population)

- Variance (sample and population)

- Root Mean Square

- Least Squares Linear Regression

- CountEach

- Histogram

Basic usage looks like:

```csharp

static void Main(string[] args)

{

    IEnumerable data = new int[] { 1, 2, 5, 6, 6, 8, 9, 9, 9 };

    Console.WriteLine("Count = {0}", data.Count());

    Console.WriteLine("Average = {0}", data.Average());

    Console.WriteLine("Median = {0}", data.Median());

    Console.WriteLine("Mode = {0}", data.Mode());

    Console.WriteLine("Sample Variance = {0}", data.Variance());

    Console.WriteLine("Sample Standard Deviation = {0}", data.StandardDeviation());

    Console.WriteLine("Population Variance = {0}", data.VarianceP());

    Console.WriteLine("Population Standard Deviation = {0}", data.StandardDeviationP());

    Console.WriteLine("Range = {0}", data.Range());

}

```

## Building

This project makes heavy use of T4 templates. You will need Visual Studio and [this extension](https://github.com/RdJNL/TextTemplatingCore) if you want to build from source. VSCode doesn't seem to support T4 templates, nor does `dotnet build`.

## Older Versions

The latest version of this library target .NET 8 LTS. If you need to target older versions of .NET, you can find the appropriate version of this library on NuGet. [Version 2.3.0](https://www.nuget.org/packages/LinqStatistics/?version=2.3.0) targets .Net Standard 1.1 and .Net Framework 4.x.
