Construct a Likelihood Object for Multinomial Data

Creates a likelihood object from a categorical variable with three or more levels, grouped by a secondary categorical variable if provided.

Usage

inz_lmulti(data, primary, secondary = NULL)

Arguments

data

A data frame containing the variables.

primary

The primary variable of interest.

secondary

An optional secondary variable of interest (for grouping).

Value

Returns an object of class "inz_lmulti".

An object of class "inz_lmulti" is a list which contains the following:

x

the count of observations in each level (as a vector or as a table if grouped).

levels

the levels of the primary variable.

groups

the levels of the secondary variable, or "none" if not grouped.

Details

Both primary and secondary must be categorical variables. They can be passed as a string (e.g. "Qualification") or as a non-string (e.g. Qualification).

The primary variable must have three or more levels. If the primary variable has only two levels, use inz_lbinom.

Examples

# Single variable
if (FALSE) inz_lmulti(surf_data, Qualification) # \dontrun{}

# Two variables (grouped data)
if (FALSE) inz_lmulti(surf_data, Qualification, Gender) # \dontrun{}
if (FALSE) inz_lmulti(surf_data, Qualification, Ethnicity) # \dontrun{}
