Overview

About

Methods and functions for fitting maximum likelihood models in R. This package modifies and extends the 'mle' classes in the 'stats4' package.

Changes in 1.0.26

NEW FEATURES

  • confint method gains a std.err argument, for use when Wald standard errors are unavailable or unreliable
  • mle2 gains a hessian.method argument, which can be set to "optimHess" when the default method (hessian or jacobian from the numDeriv package) is unreliable

BUG FIXES

  • added a nobs method for mle2 objects; its absence made BICtab/ICtab(type="BIC") fail unconditionally, and made AICc/qAICc fall back to unreliable heuristics (GH #35)
  • ICtab(type="BIC") now respects an explicit nobs argument, instead of silently ignoring it (GH #35)
  • fixed inconsistent degrees-of-freedom adjustment in qAICc, which caused qAICc() on a single object to disagree with qAICc() on multiple objects (GH #22)
  • mle2(optimizer="optimx") now checks up front that the requested method(s) are recognized and that any packages they require (e.g. minqa for "bobyqa"/"newuoa", BB for "spg", ucminf for "ucminf", dfoptim for "nmkb"/"hjkb") are installed, instead of silently returning NA parameter estimates; a generic check also now catches NA parameter results from any optimizer (GH #31)
