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.
