mvnfit {networktree}

Maximum Likelihood Estimation for Multivariate Normal Model

Description

Fit a multivariate normal model without covariates or covariance restrictions. In addition to the (straightforward) parameter estimates the fitted log-likelihood and corresponding score contributions are computed.

Usage

mvnfit(
  y,
  x = NULL,
  start = NULL,
  weights = NULL,
  offset = NULL,
  model = c("correlation", "mean", "variance"),
  ...,
  estfun = FALSE,
  object = FALSE
)

Arguments
