propfit: Fit Proportions.

In meteosimon/proptree: Regression Trees of Proportions

Description

Maximum likelihood estimation of Dirichlet parameter.

Usage

propfit(
  y,
  x = NULL,
  start = NULL,
  weights = NULL,
  offset = NULL,
  ...,
  estfun = FALSE,
  object = FALSE
)

Arguments

y	A matrix or data.frame where each row corresponds to a k-dim observation.
x	Not used.
start	Not used.
weights	Not used yet.
offset	Not used.
...	Not used yet.
estfun	logical. Should the matrix of score contributions (estimating functions) be returned.
object	logical. Should the return from 'optim()' be returned.

Details

Perform MLE of parameters of a Dirichlet distribution. Interface and return value are designed to fit the modelparty infrastructure of the partykit package. ML estimates are found numerically using 'optim' with BFGS algorithm.
