ApproxF: Calculate ANOVA with approximate F value

In EMSaov: The Analysis of Variance with EMS

Description

Calculate ANOVA with approximate F value

Usage

ApproxF(SS.table,approx.name)

Arguments

SS.table	result from EMSanova
approx.name	rowname in SS.table to calculate approximate F value for the test.

Examples

data(film)
anova.result<-EMSanova(thickness~Gate*Operator*Day,data=film,
                        type=c("F","R","R"))
anova.result                         
ApproxF(SS.table=anova.result,approx.name="Gate") 
EMSanova(thickness~Gate+Operator+Day,data=film,
          type=c("F","R","R"),
          approximate=TRUE)
