parameters-methods: Parameter values for MPT models

In MPTinR2: Analyze Multinomial Processing Tree Models

Description

Generic function to display the parameter values and confidence intervals for MPT models.

Usage

## S4 method for signature 'mpt'
parameters(object, ci = NULL, show.equality = FALSE, show.fixed = TRUE, sort.alphabetical = FALSE, ...)
## S4 method for signature 'bmpt'
parameters(object, type = c("nonparametric", "parametric", "fisher"), ci = NULL, show.equality = FALSE, show.fixed = TRUE, sort.alphabetical = FALSE, ...)

Arguments

object	object of class mpt or bmpt
type	type of confidence interval to be displayed. Other types than fisher are only possible for objects of class bmpt and when the relevant calculations have already been done (which are currently not implemented).
ci	numeric or NULL. Size of confidence interval. If NULL (the default) the value is taken from objects's slot default.ci (default = 95).
show.equality	Logical. Should all parameters that are euqal to other be displayed? If FALSE (the default) only the parameter that is estimated is displayed and all that are equal to this one ommited.
show.fixed	Logical. Should parameters that are restricted to a value be displayed?
sort.alphabetical	Logical. Should parameters be orderd alphabetical? If FALSE (the default), the order of parameters is: 1. free parameters, 2. inequality restricted parameters, 3. equality restricted parameters, 4. fixed.parameters.
...	ignored.

Details

Convenience function that displayes parameter values plus confidence intervals. Parameters that are restricted are marked in the output (1 = fixed parameter, 2 = equality restricted parameter, 3 = inequality restricted parameter).

Value

For a signle fit a data.frame with four columns: estimated parameter values, lower bound of the confidence interval, upper bound of the confidence interval, type of parameter.

For mutliple fits a list with three items. The columns are the same as for single fits.

individual	A 3-dimensional (named) array with the value for each individual, with dimensions: (parameter, column, individual)
mean	mean parameter values
aggregated	values for the aggregated data
