Confidence intervals for tow way ANOVA

Description

Confidence intervals for tow way ANOVA.

Estimation and confidense interval of Factor Level Mean.

Estimation and confidense interval of Contrast of Factor Level Means

Estimation and confidense interval of linear Combination of Factor level Means

Multiple Pairwise Comparisons and confidense interval of Factor level Means (Tukey and Bonferroni Procedurs)

Multiple Contrasts and confidense interval of Factor Level Means (scheffe and Bonferroni Procedurs)

Etimates and confidense interval Based on Treatment Means

Interactions Are Important:

Multiple Pairwise Comparisons of Treatment Means(Tukey and Bonferroni Procedure.)

Multiple Contrasts of Treatment Means(Scheffe and Bonferroni Procedure.)

Usage

towway.ci(y, x1, x2, mc = NULL, mp = NULL,mt=NULL, mse= NULL,alpha = 0.05)

Arguments
