Compute the probability density function of a matrix of features.
pdfunc(x, univariate = TRUE)
x | A matrix of numeric features. |
---|---|
univariate | Logical indicating whether the univariate pdf should be computed. |
A vector with values of the density function.
pdfunc
computes univariate or multivariate probabilities for a set of
observations.
All columns of a row are used in computing the pdf.
Variance and covariance are computed using var
and cov
, where
the denominator n-1
is used.
