.idx

Logical; should the indices of fixed parameters also be returned?

fixed

pargroup

Parameter names or indices within groups

which

Is partial matching allowed for <code>which</code>

pmatch

Alternative parameterizations (currently only "lm" possible)

altpar

If fixed is logical, it inidcates that the indices refer to the extended
parameter vector
pargroup = c("fixef", "ranef", "shift", "all")

Likelihood-based estimation of mixed-effects transformation models using the Template
Model Builder ('TMB', Kristensen et al., 2016, <doi:10.18637/jss.v070.i05>). The technical details
of transformation models are given in Hothorn et al. (2018, <doi:10.1111/sjos.12291>). Likelihood
contributions of exact, randomly censored (left, right, interval) and truncated observations are
supported. The random effects are assumed to be normally distributed on the scale of the
transformation function, the marginal likelihood is evaluated using the Laplace approximation,
and the gradients are calculated with automatic differentiation (Tamasi and Hothorn, 2021,
<doi:10.32614/RJ-2021-075>). Penalized smooth shift terms can be defined using 'mgcv'.
