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:
static void Main(string[] args)
{
IEnumerable<int> 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());
}
