## S3 method for class 'mlds':
predict(object, newdata = NULL, type = "link", ...)
Arguments
object
object of class mlds, typically from the output of mlds
newdata
A data.frame or object of class mlds.df with 5 columns, corresponding to the response at each trial and the ranks of the quadruple of stimuli presented.
type
character indicating scale on which predictions should be made, link, the default, on the scale of the linear predictor or response, on the response scale.
...
When obj$method = glm, these are additional arguments passed to predict.glm.
Value
A numeric vector of the predicted values either on the scale of the linear predictor or on the response scale.
Details
The newdata argument is needed principally for the 6-point test (see lik6pt), to extract the estimated probabilities for the subsets of the original data that form valid 6-point tests.
