mclust (version 6.1)

map: Classification given Probabilities

Description

Converts a matrix in which each row sums to 1 to an integer vector specifying for each row the column index of the maximum.

Usage

map(z, warn = mclust.options("warn"), ...)

Value

A integer vector with one entry for each row of z, in which the i-th value is the column index at which the

i-th row of z attains a maximum.

Arguments

z

A matrix (for example a matrix of conditional probabilities in which each row sums to 1 as produced by the E-step of the EM algorithm).

warn

A logical variable indicating whether or not a warning should be issued when there are some columns of z for which no row attains a maximum.

...

Provided to allow lists with elements other than the arguments can be passed in indirect or list calls with do.call.
