What is the meaning of analysis of covariance?
A mix of linear regression and analysis of variance. analysis of covariance is responsible for intergroup variance when analysis of variance is performed.
What is heteroscadacity?
In regression analysis , heteroscedasticity means a situation in which the variance of the dependent variable varies across the data. Heteroscedasticity complicates analysis because many methods in regression analysis are based on an assumption of equal variance.
Example of parametric test?
The Fisher F-test for Analysis of Variance (ANOVA).
What is the F stat in regression analysis?
The F stat tests the equality of variances. It uses statistical tables for reference and is calculated with F = Variance 1 (max)/variance 2(min).
Basic assumption in analysis of variance?
1- observations are from normally distributed populations. 2- observations are from populations with equal variances.
What is the meaning of analysis of covariance?
A mix of linear regression and analysis of variance. analysis of covariance is responsible for intergroup variance when analysis of variance is performed.
What has the author Hardeo Sahai written?

Distinguish between analysis of variance and analysis of covariance?

An analysis of variance differs from a t test for independent means in that an analysis of variance?
Analysis of Variance (ANOVA) compares 3 or more means. The t-test would only compare 2 means.
What are the variances in a 4 variance analysis?
efficiency variance, spending variance, production volume variance, variable and fixed components
