MathNet用到的一些功能

1、计算一元线性函数

Tuple<double, double> myLineTuple = MathNet.Numerics.Fit.Line(myXArray, myYArray);

double myA = myLineTuple.Item1;

double myB = myLineTuple.Item2;

2、常用统计函数

统计最小值、最大值、平均值、分位数等

double myMinimum = MathNet.Numerics.Statistics.Statistics.Minimum(myValueList);

double myMean = MathNet.Numerics.Statistics.Statistics.Mean(myValueList);

double myMaximum = MathNet.Numerics.Statistics.Statistics.Maximum(myValueList);

double myLowerQuartile = MathNet.Numerics.Statistics.Statistics.LowerQuartile(myValueList);

double myMedian = MathNet.Numerics.Statistics.Statistics.Median(myValueList);

double myUpperQuartile = MathNet.Numerics.Statistics.Statistics.UpperQuartile(myValueList);

MathNet.Numerics.Statistics.Statistics.Quantile(this.ValueList,0.2)

3、求两组样品的相关系数

MathNet.Numerics.Statistics.Correlation.Pearson(pValueList1, pValueList2);

4、根据相关性矩阵，求特征值以及特征向量

public void CalEigenValue(double[,] pCorrelationArray)

{

    var myCorrelationMatrix = DenseMatrix.OfArray(pCorrelationArray);

    var myEvd = myCorrelationMatrix.Evd();

    for (int i = 0; i < this.FactorList.Count; i++)

    {

        FactorAnalysisFactor myFactor = this.FactorList[i];

        myFactor.EigenValue = myEvd.D[i, i];

        myFactor.EigenValueArray = myEvd.EigenVectors.Column(i).ToArray();

    }

}
