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.
	FisherStatistics	The FisherStatistics property returns Fisher statistics value.
	Probability	The Probability property returns probability.
	SumSquared	The SumSquared property returns the sum of deviation squares.
	UnbiasedEstimation	The UnbiasedEstimation property returns the unbiased estimated sum of deviation squares.
	VarianceEqualByColumns	The VarianceEqualByColumns property returns the result indicating whether the hypothesis on the equality of B factor variances is accepted.
	VarianceEqualByRows	The VarianceEqualByRows property returns whether the hypothesis on the equality of group means or the equality of variances (depending on the analysis type) is accepted.
