heplots-internal: Internal heplots functions

Description

Internal functions for the heplots package

Usage

lambda.crit(
  alpha,
  p,
  dfh,
  dfe,
  test.statistic = c("Roy", "HLT", "Hotelling-Lawley")
)
Roy.crit(alpha, p, dfh, dfe)
HLT.crit(alpha, p, dfh, dfe)
he.rep(x, n)
Pillai(eig, q, df.res)
Wilks(eig, q, df.res)
HL(eig, q, df.res)
Roy(eig, q, df.res)

Value

The critical value of the test statistic

Arguments

alpha

significance level for critical values of multivariate statistics

p

Number of variables

dfh

degrees of freedom for hypothesis

dfe

degrees of freedom for error

test.statistic

Test statistic used for the multivariate test

x

An argument to heplot or heplot3d that is to be repeated for Error and all hypothesis terms

n

Number of hypothesis terms

Details

These functions calculate critical values of multivariate test statistics (Wilks' Lambda, Hotelling-Lawley trace, Roy's maximum root test) used in setting the size of H ellipses relative to E. They are not intended to be called by the user.
