Class that represents the Variance statistical function. The variance of a random sample or population variable is a non-negative number which gives an idea of how widely spread the values of the random variable are likely to be; the larger the variance, the more scattered the observations on average.

System.Object
Xceed.Wpf.DataGrid.Stats.StatFunction
Xceed.Wpf.DataGrid.Stats.VarianceFunction
| Name | Description | |
|---|---|---|
 | VarianceFunction Constructor | Overloaded. Initializes a new instance of the VarianceFunction class. |
| Name | Description | |
|---|---|---|
 | EntirePopulation | Gets or sets a value indicating whether the variance is calculated for an entire population. |
| ResultPropertyName | Gets or sets the unique, case-sensitive property name from which the result of the function can be retrieved. (Inherited from Xceed.Wpf.DataGrid.Stats.StatFunction) |
| SourcePropertyName | Gets or sets the name of the column whose values will be used to calculate the result. (Inherited from Xceed.Wpf.DataGrid.Stats.StatFunction) |
| Name | Description | |
|---|---|---|
 | IsInitialized | Gets a value indicating whether Initialize method has been called, indicating that the types in which the values will be accumulated have been initialized. (Inherited from Xceed.Wpf.DataGrid.Stats.StatFunction) |
 | IsSealed | Gets a value indicating whether this instance is in an immutable state. (Inherited from Xceed.Wpf.DataGrid.Stats.StatFunction) |
| PrerequisiteFunctions | Overridden. Gets a list of the statistical functions whose results are required by the current statistical function in order to calculate its own result. |
| RequiresAccumulation | Gets a value indicating whether the statistical function needs to accumulate its own results. (Inherited from Xceed.Wpf.DataGrid.Stats.StatFunction) |
| Name | Description | |
|---|---|---|
 | Accumulate | Overridden. Accumulates the values required to calculate the result of the statistical function. |
 | CheckSealed | Checks whether this object is read-only and cannot be changed. (Inherited from Xceed.Wpf.DataGrid.Stats.StatFunction) |
| GetEquivalenceKey | Retrieves a value that represents the statistical function's unique equivalence key. (Inherited from Xceed.Wpf.DataGrid.Stats.StatFunction) |
| GetResult | Overridden. Retrieves the result of the statistical function. |
| Initialize | Overridden. Initializes the statistical function specifying the types of the columns specified by the SourcePropertyName property. |
| InitializeFromInstance | Overridden. Initializes the properties of the current instance of the same-type statistical function when child results are being calculated. |
| InitializePrerequisites | Overridden. Initializes the prerequisite statistical functions defined by the PrerequisiteFunctions property. |
| IsEquivalent | Overridden. Retrieves a value indicating whether a statistical function is the equivalent of the current statistical function such that both statistical functions will return the same result for the same set of values. |
| Reset | Overridden. Resets the statistical function to its original state. |
| Validate | Overridden. Validates the statistical function to ensure that it is able to calculate its result. |
