    distribution = c("norm", "t", "f", "chisq"), ...)

Arguments

`statistics`	vector of test statistics
`samplesize`	total sample size of the pilot-data or effective sample size in two-group case (see Details for more information).
`distribution`	type of the null/alternative distribution, one of 'norm', 't', 'f' or 'chisq'
`...`	additional arguments for the distribution like degrees of freedom

Details

In the two-group case the effective sample size is defined as the square-root of the inverse of 1/n1 + 1/n2.

Value

object of class "PilotData"

Examples

pd <- pilotData(statistics=rnorm(100), samplesize=10, distribution="norm")
pd
plot(pd)
