Methods
| Icon | Type | Description |
|---|---|---|
 | CalculateStatistic() |
Calculates the value of the statistic used for this test.
|
 | Equals(Object) | |
| Finalize() | |
| GetConfidenceInterval(Double) |
Returns the confidence interval for the variance of the population for the specified confidence level.
|
| GetHashCode() | Serves as a hash function for a particular type. |
| GetLowerCriticalValue() |
Gets the lower critical value for the hypothesis test's current significance level.
|
| GetLowerCriticalValue(Double) |
Gets the lower critical value for the hypothesis test at the specified significance level.
|
| GetType() | Gets the Type of the current instance. |
| GetUpperCriticalValue() |

|
| GetUpperCriticalValue(Double) |
Gets the upper critical value for the test statistic at the specified significance level.
|
| MemberwiseClone() | Creates a shallow copy of the current Object. |
| Reject() |
Returns a value that indicates whether the null hypothesis is rejected
using the default significance level.
|
| Reject(Double) |
Returns a value that indicates whether the null hypothesis is rejected using the specified significance level.

Constructors
| Icon | Type | Description |
|---|---|---|
| OneSampleChiSquareTestNew() |

Properties
| Icon | Type | Description |
|---|---|---|
 | Distribution |
Sets the probability distribution used in the hypothesis test.
|
| HypothesisType |
Gets or sets a value that indicates whether the test is one or two-tailed.
|
| PValue |
Gets the probability that the test statistic would take on the calculated value under the null hypothesis.
|
| Sample |
Gets or sets the variable the test is to be applied to.
|
| SampleSize |
Gets or sets the size of the sample.
|
| SampleVariance |
Gets or sets the variance of the sample.
|
| SignificanceLevel |
Gets the significance level used to test the null hypothesis.
|
| Statistic |
Gets the value of the test statistic.
|
| Variance |
Gets or sets the proposed variance.
|
Remarks
Use the OneSampleChiSquareTest class to test the hypothesis
that the variance of a variable variable is equal to a specified value.
The sample data can be supplied either as a NumericalVariable, or by specifying the SampleVariance and the SampleSize.
A confidence interval for the variance of the sample can be obtained using the GetConfidenceInterval(Double) method.
