Comments

The analysis executes the standard procedure of factor variance analysis. Specify observations and confidence level required to estimate the critical parameters of F-statistics. The result is the required statistical data and a logical value determining whether the null hypothesis on the equality of variances (two-factor analysis) or on the equality of group means (single-factor analysis) should be accepted or rejected.

Properties

  Property name Brief description
AnalysisType The AnalysisType property determines the type of variance analysis.
ConfidenceLevel The ConfidenceLevel property determines the significance level determining whether the null hypothesis should be accepted or rejected.
Data The Data property determines analyzed observations.
DegreeOfFreedom The DegreeOfFreedom property returns the number of degrees of freedom.
FisherCritical The FisherCritical property returns the critical value for the Fisher statistics.
