BAMLSS Model Frame

Extracts the model frame of a bamlss or bamlss.frame object.

# S3 method for bamlss
model.frame(formula, ...)

# S3 method for bamlss.frame
model.frame(formula, ...)

## Internal helper function for creating
## the model frame.
bamlss.model.frame(formula, data, family = gaussian_bamlss(),
  weights = NULL, subset = NULL, offset = NULL,
  na.action = na.omit, specials = NULL, contrasts.arg = NULL,
  drop.unused.levels = TRUE, ...)

Arguments

formula: An object of class "bamlss" or "bamlss.frame".
data: A data.frame or list containing the model response variable(s) and covariates specified in the formula. By default the variables are taken from environment(formula).
family: A bamlss.family object, see function bamlss.
weights: Prior weights on the data.
subset: An optional vector specifying a subset of observations to be used in the fitting process.
offset: Can be used to supply model offsets for use in fitting.
na.action: A function which indicates what should happen when the data contain NA's. The default is set by the na.action setting of options, and is na.omit if set to NULL.
specials: Special function in formulas, see terms.object.
contrasts.arg: An optional list. See the contrasts.arg of model.matrix.default.
drop.unused.levels: Should factors have unused levels dropped?
...: Arguments to be passed to bamlss.model.frame() and others.

Value

The data.frame containing the variables used for modeling with function bamlss.

Examples

if (FALSE) ## Generate some data.
d <- GAMart()

## Model formula.
f <- list(
  log(pnum) ~ s(x1) + log(x2),
  sigma ~ s(x3)
)

## Estimate model.
b <- bamlss(f, data = d)
#> Error in eval(expr, envir, enclos): object 'd' not found

## Extract the model frame.
head(model.frame(b))
#> Error in eval(expr, envir, enclos): object 'b' not found
