Description

randtest is a generic function. It proposes methods for the following objects between, discrimin, coinertia ...

Usage

randtest(xtest, ...)
    plot.randtest(x, nclass = 10, coeff = 1, ...)
    as.randtest (sim, obs,alter=c("greater", "less", "two-sided"), call = match.call())
    print.randtest (x, ...)

Arguments

xtest

an object used to select a method

x

an object of class randtest

...

... further arguments passed to or from other methods; in plot.randtest to hist

nclass

a number of intervals for the histogram

coeff

to fit the magnitude of the graph

sim

a numeric vector of simulated values

obs

a numeric vector of an observed value

alter

a character string specifying the alternative hypothesis, must be one of "greater" (default), "less" or "two-sided"

call

a call order

Value

• as.randtest returns a list of class randtest plot.randtest draws the simulated values histograms and the position of the observed value
