summary.emMSmix function

Summary of the fitted mixture of Mallows models with Spearman distance

summary method for class "emMSmix".

print method for class "summary.emMSmix".

## 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.

Returns

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)
