Description Usage Arguments Details Value Author(s) See Also Examples

Updates a given expectreg model with the specified changes

## S3 method for class 'expectreg'
update(object, add_formula, data = NULL, estimate = NULL, 
smooth = NULL, lambda = NULL, expectiles = NULL, delta_garrote = NULL, ci = NULL, 
...)

`object`	of class expectreg
`add_formula`	update for formula
`data`	Should other data be used
`estimate`	Change estimate
`smooth`	Change smooth
`lambda`	Change lambda
`expectiles`	Change asymmetries
`delta_garrote`	Change delta_garrote
`ci`	Change ci
`...`

Re-estimates the given model, with the specified changes. If nothing is specified the characteristics of the original model are used. Except lambda here the default 1 is used as initial value.
