startParams {glmmTMB} | R Documentation |
Change starting parameters, either by residual method or by user input (start)
Description
Change starting parameters, either by residual method or by user input (start)
Usage
startParams(
parameters,
formula,
ziformula,
dispformula,
fr,
yobs,
weights,
size = NULL,
Xdisp = NULL,
XdispS = NULL,
family,
condReStruc,
start = NULL,
sparseX = NULL,
start_method = list(method = NULL, jitter.sd = 0)
)
Arguments
formula |
current formula, containing both fixed & random effects |
ziformula |
a one-sided (i.e., no response variable) formula for zero-inflation combining fixed and random effects: the default |
dispformula |
a one-sided formula for dispersion combining fixed and random effects: the default |
fr |
model frame |
yobs |
observed y |
weights |
model weights (for binomial-type models, used as size/number of trials) |
size |
number of trials in binomial and betabinomial families |
family |
family object |
start |
starting values, expressed as a list with possible components |
sparseX |
see |
start_method |
Options to initialise the starting values for rr parameters; jitter.sd adds variation to the starting values of latent variables when start = "res". |
