Control Parameters for the Fitting Process¶
Description¶
mclogit.control
returns a list of default parameters that control the fitting process
of mclogit
.
Usage¶
mclogit.control(epsilon = 1e-08,
maxit = 25, trace=TRUE)
mmclogit.control(epsilon = 1e-08,
maxit = 25, trace=TRUE,
trace.inner=FALSE,
avoid.increase = FALSE,
break.on.increase = FALSE,
break.on.infinite = FALSE,
break.on.negative = FALSE)
Arguments¶
epsilon
-
positive convergence tolerance \(\epsilon\); the iterations converge when \(|dev - dev_{old}|/(|dev| + 0.1) < \epsilon\).
maxit
-
integer giving the maximal number of IWLS or PQL iterations.
trace
-
logical indicating if output should be produced for each iteration.
trace.inner
-
logical; indicating if output should be produced for each inner iteration of the PQL method.
avoid.increase
-
logical; should an increase of the deviance be avoided by step truncation?
break.on.increase
-
logical; should an increase of the deviance be avoided by stopping the algorithm?
break.on.infinite
-
logical; should an infinite deviance stop the algorithm instead of leading to step truncation?
break.on.negative
-
logical; should a negative deviance stop the algorithm?
Value¶
A list.
