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)

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.
