Summary of the fitted mixture of Mallows models with Spearman distance

Description

summary method for class "emMSmix".

print method for class "summary.emMSmix".

Usage

## S3 method for class 'emMSmix'
summary(object, digits = 3, ...)

## S3 method for class 'summary.emMSmix'
print(x, ...)

Arguments

object	An object of class "emMSmix" returned by fitMSmix.
digits	Integer: decimal places for rounding the numerical summaries. Defaults to 3.
...	Further arguments passed to or from other methods (not used).
x	An object of class "summary.emMSmix" returned by summary.emMSmix.

Value

A list with the following named components:

modal_rankings	Integer matrix with the MLEs of the G component-specific consensus rankings in each row.
modal_orderings	Character matrix with the MLEs of the G component-specific consensus orderings in each row.
theta	Numeric vector of the MLEs of the G precisions.
weights	Numeric vector of the MLEs of the G mixture weights.
MAP_distr	Percentage distribution of the component memberships based on the MAP allocation. Returned when n_clust > 1, otherwise NULL
conv_perc	Percentage of convergence of the EM algorithm over the multiple starting points.
BIC	BIC value (based on full or augmented rankings).
BIC_part	BIC value (based on partial rankings).
call	The matched call.

Examples

## Example 1. Fit and summary of a 3-component mixture of Mallows models with Spearman distance
## for the Antifragility dataset.
r_antifrag <- ranks_antifragility[, 1:7]
set.seed(123)
mms_fit <- fitMSmix(rankings = r_antifrag, n_clust = 3, n_start = 10)
summary(mms_fit)
