StatisticFormula Class

.NET Framework 4.6 and 4.5

Calculates statistical formulas.


Namespace:  System.Windows.Forms.DataVisualization.Charting
Assembly:  System.Windows.Forms.DataVisualization (in System.Windows.Forms.DataVisualization.dll)

public class StatisticFormula

The StatisticFormula type exposes the following members.

Public methodAnovaPerforms an ANOVA test to determine whether there is a statistically significant difference between the mean values of two or more groups of data.
Public methodBetaFunctionReturns the beta function value for two given values.
Public methodCorrelationReturns the correlation value for two data series.
Public methodCovarianceReturns the covariance value for two data series.
Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Public methodFDistributionReturns the cumulative F distribution function probability.
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodFTestPerforms a two-sample F Test using the F distribution. This test is used to determine if the samples have different variances.
Public methodGammaFunctionReturns the gamma function value for the given variable.
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodInverseFDistributionReturns the inverse of the F cumulative distribution.
Public methodInverseNormalDistributionReturns the inverse of the standard normal cumulative distribution.
Public methodInverseTDistributionReturns the inverse t-value of the Students t-distribution as a function of probability and degree of freedom.
Public methodMeanReturns the average of all data points stored in the specified series.
Public methodMedianReturns the median of all data points in the specified series.
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodNormalDistributionReturns the probability for the standard normal cumulative distribution function.
Public methodTDistributionReturns the probability for the T distribution (Student's distribution).
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)
Public methodTTestEqualVariancesPerforms a T Test using Student's distribution (T distribution) with equal variances.
Public methodTTestPairedPerforms a T Test using Student's distribution (T distribution) with paired samples. This is useful when there is a natural pairing of observations in samples.
Public methodTTestUnequalVariancesPerforms a T Test using Student's distribution (T distribution) with unequal variances.
Public methodVarianceReturns the variance for a series.
Public methodZTestPerforms a Z Test using the Normal distribution.

Formulas can be loosely grouped into the following categories: distributions, including inverse distributions; tests; and basic statistical formulas. Each group has common characteristics with respect to their input and return values.
