qHardRoqF

Number of observations used in the computation of the raw MCD Mahalanobis squared distances.

nobs

Number of variables used in the computation of the raw MCD Mahalanobis squared distances.

nvar

Number of observations kept in the computation of the raw MCD estimate.

logical; if TRUE (default) returns the quantile of the adjusted distribution. Otherwise returns the quantile of the asymptotic distribution.

logical; if TRUE (default), probabilities are P(X &lt;= x) otherwise, P(X &gt; x)

lower.tail

logical; if TRUE, probabilities p are given as log(p).

log.p

p-quantiles of the Hardin and Rocke (2005) scaled F distribution for squared Mahalanobis distances based on raw MCD covariance estimators

Implements methodologies for modelling interval data by Normal
and Skew-Normal distributions, considering appropriate parameterizations of
the variance-covariance matrix that takes into account the intrinsic nature of
interval data, and lead to four different possible configuration structures.
The Skew-Normal parameters can be estimated by maximum likelihood, while Normal
parameters may be estimated by maximum likelihood or robust trimmed maximum
likelihood methods.
