Standard Normal Distribution z-value function in C#

Question

I been looking at the recent blog post by Jeff Atwood on Alternate Sorting Orders. I tried to convert the code in the post to C# but I ran into an issue. There is no function in

Answer 1

if you are using Math.Net then you can just use the InverseCumulativeDistribution function.

So if you want the Z-value, where 80% of the Standard Normal curve is covered the code would look something like this

var curve = new MathNet.Numerics.Distributions.Normal();
var z_value = curve.InverseCumulativeDistribution(0.8);
Console.WriteLine(z_value);

Ensure that you have installed the MathNet.Numerics NuGet package.
