Given an object of class RprobitB_fit, this function can:

• change the length B of the burn-in period,

• change the the thinning factor Q of the Gibbs samples,

• change the utility scale.

## Usage

# S3 method for RprobitB_fit
transform(
_data,
B = NULL,
Q = NULL,
scale = NULL,
check_preference_flip = TRUE,
...
)

## Arguments

_data

An object of class RprobitB_fit.

B

The length of the burn-in period, i.e. a non-negative number of samples to be discarded.

Q

The thinning factor for the Gibbs samples, i.e. only every Qth sample is kept.

scale

A character which determines the utility scale. It is of the form <parameter> := <value>, where <parameter> is either the name of a fixed effect or Sigma_<j>,<j> for the <j>th diagonal element of Sigma, and <value> is the value of the fixed parameter.

check_preference_flip

Set to TRUE to check for flip in preferences after new scale.

...

Ignored.

## Value

The transformed RprobitB_fit object.
