ファイルから取得した値が範囲内に入るかどうかを確認する

Question

したがって、ファイルから取得した値が特定の範囲内にあるかどうかを判断するコードを記述する必要があります。

   double averageMaximumX = query.Average(t => double.Parse(t.XMax)); 
    double varianceMaximumX = query.Sum(t => Math.Pow(double.Parse(t.XMax) - averageMaximumX, 2)); 
       varianceMaximumX /= query.Count(); 
       double stdDevMaximumX = Math.Sqrt(varianceMaximumX); 

       double averageMinimumX = query.Average(t => double.Parse(t.XMin)); 
    double varianceMinimumX = query.Sum(t => Math.Pow(double.Parse(t.XMin) - averageMinimumX, 2)); 
       varianceMinimumX /= query.Count(); 
       double stdDevMinimumX = Math.Sqrt(varianceMinimumX); 

       double averageMaximumY = query.Average(t => double.Parse(t.YMax)); 
    double varianceMaximumY = query.Sum(t => Math.Pow(double.Parse(t.YMax) - averageMaximumY, 2)); 
       varianceMaximumY /= query.Count(); 
       double stdDevMaximumY = Math.Sqrt(varianceMaximumY); 

       double averageMinimumY = query.Average(t => double.Parse(t.YMin)); 
    double varianceMinimumY = query.Sum(t => Math.Pow(double.Parse(t.YMin) - averageMinimumY, 2)); 
       varianceMinimumY /= query.Count(); 
       double stdDevMinimumY = Math.Sqrt(varianceMinimumY); 

       double averageMaximumZ = query.Average(t => double.Parse(t.ZMax)); 
    double varianceMaximumZ = query.Sum(t => Math.Pow(double.Parse(t.ZMax) - averageMaximumZ, 2)); 
       varianceMaximumZ /= query.Count(); 
       double stdDevMaximumZ = Math.Sqrt(varianceMaximumZ); 

       double averageMinimumZ = query.Average(t => double.Parse(t.ZMin)); 
    double varianceMinimumZ = query.Sum(t => Math.Pow(double.Parse(t.ZMin) - averageMinimumZ, 2)); 
       varianceMinimumZ /= query.Count(); 
       double stdDevMinimumZ = Math.Sqrt(varianceMinimumZ); 


       var results = from item in query 
           select new 
           { 
     XMaxResult = TryParseWithDefault(item.XMax, double.NaN) <= averageMaxX ? "pass" : "FAIL", 
     XMinResult = TryParseWithDefault(item.XMin, double.NaN) >= averageMinX ? "pass" : "FAIL", 
     YMaxResult = TryParseWithDefault(item.YMax, double.NaN) <= averageMaxY ? "pass" : "FAIL", 
    YMinResult = TryParseWithDefault(item.YMin, double.NaN) >= averageMinY ? "pass" : "FAIL", 
     ZMaxResult = TryParseWithDefault(item.ZMax, double.NaN) <= averageMaxZ ? "pass" : "FAIL", 
     ZMinResult = TryParseWithDefault(item.ZMin, double.NaN) >= averageMinZ ? "pass" : "FAIL" 

           };

平均に標準偏差を加算します。

例

XMaxResult = (TryParseWithDefault(item.XMax, double.NaN) <= averageMaxX + stdDevMaximumX 
      && TryParseWithDefault(item.XMax, double.NaN) >= averageMaxX - stdDevMaximumX) 
      ? "pass" : "FAIL"
