transform function

Transform fitted probit model

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.

## S3 method for class '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.

Returns

The transformed RprobitB_fit object.
