Usage
clmm2.control(method = c("ucminf", "nlminb", "model.frame"), ...,
trace = 0, maxIter = 50, gradTol = 1e-4,
maxLineIter = 50,
innerCtrl = c("warnOnly", "noWarn", "giveError"))Arguments
- method
the optimizer used to maximize the marginal likelihood function.
- …
control arguments passed on to the chosen optimizer; see
ucminf,optim, andnlminbfor details.- trace
numerical, if > 0 information is printed about and during the outer optimization process, if < 0 information is also printed about the inner optimization process. Defaults to
0.- maxIter
the maximum number of Newton updates of the inner optimization.
50.- gradTol
the maximum absolute gradient of the inner optimization.
- maxLineIter
the maximum number of step halfings allowed if a Newton(-Raphson) step over shoots during the inner optimization.
- innerCtrl
the use of warnings/errors if the inner optimization fails to converge.
Details
When the default optimizer, ucminf is used, the default values
of that optimizers control options are changed to grtol = 1e-5
and grad = "central".
Value
a list of control parameters.
