In NPflow: Bayesian Nonparametrics for Automatic Gating of Flow-Cytometry Data

Description

multivariate skew-t probability density function

Usage

mvstpdf(x, xi, sigma, psi, df, Log = TRUE)

Arguments

x	p x n data matrix with n the number of observations and p the number of dimensions
xi	mean vector or list of mean vectors (either a vector, a matrix or a list)
sigma	variance-covariance matrix or list of variance-covariance matrices (either a matrix or a list)
psi	skew parameter vector or list of skew parameter vectors (either a vector, a matrix or a list)
df	a numeric vector or a list of the degrees of freedom (either a vector or a list)
Log	logical flag for returning the log of the probability density function. Defaults is TRUE.
