C# Example

The following example calculates coefficients for simple logistic regression. The counts are out of 10 in each case and there is one covariate[1].

using Dew.Math;
using Dew.Stats;
using Dew.Stats.Units;
namespace Dew.Examples
{
  private void Example()
  {
    Vector y = new Vector(0);
    Vector n = new Vector(0);
    Vector B = new Vector(0);
    Matrix X = new Matrix(0,0);
    y.SetIt(false,new double[] {2,0,3,1,5,5,6,9,5,9});
    n.Size(y);
    n.SetVal(10.0);
    X.SetIt(false,10,2, new double[]
          {1,1,
          1,2,
          1,3,
          1,4,
          1,5,
          1,6,
          1,7,
          1,8,
          1,9,
          1,10});
    Regress.LogisticRegress(y,n,B,null);
    // B = (-2.58,0.42)
  }
}
