plot_radar_int_Shapley: Radar plot of Shapley values for interval-valued data.

In AIDA: Analysis of Interval DAta

Radar plot of Shapley values for interval-valued data.

Description

Radar plot of Shapley values for interval-valued data.

Usage

plot_radar_int_Shapley(shapley, palette = NULL, sort.obs = FALSE)

Arguments

shapley	A n \times p matrix containing the Shapley values of n observations and p variables.
palette	A vector of palette for each observation. Default is black.
sort.obs	Logical. If TRUE (default), observations are sorted according to their squared (robust) Interval-Mahalanobis distance.

Value

Returns a radar plot that displays the Shapley values (int_Shapley) for each observation.

Examples

# Create intData object
data(creditcard)
credit_card_int <- creditcard$intData

# Estimate the mean and covariance matrix
credit_card_IMCD <- IMCD(credit_card_int, 
                         m = floor(nrow(credit_card_int)*0.75), 
                         cutoff = "farness", 
                         cutoff_lvl = 0.9)

# Detect outliers using farness cutoff
credit_card_outliers <- int_outliers(credit_card_IMCD$robust_dist, 
                                     cutoff = "farness", 
                                     cutoff_lvl = 0.9)

# Compute Shapley values
credit_card_shapley <- int_Shapley(credit_card_int, 
                                   mean_c = credit_card_IMCD$mean_IMCD_c,
                                   mean_r = credit_card_IMCD$mean_IMCD_r, 
                                   cov = credit_card_IMCD$cov_IMCD)

# colors
outliers_colors <- rep('black',credit_card_int@NObs)
names(outliers_colors) <- rownames(credit_card_int)
outliers_colors[credit_card_outliers$outliers_names] = '#009de0'

plot_radar_int_Shapley(credit_card_shapley, palette = outliers_colors)
