Report Reference-Feature Alignment Coverage
Value
A data frame with the number and fraction of subjects supporting each reference feature and the aggregate sparse-map weight. Shared alignment reports complete support.
Examples
example_data <- design_mfa_example_data()
identity_maps <- lapply(example_data$Y, function(y) {
P <- Matrix::Diagonal(ncol(y))
dimnames(P) <- list(colnames(y), colnames(y))
P
})
names(identity_maps) <- names(example_data$Y)
soft_fit <- design_mfa(
example_data$Y, example_data$design, ~ saliency,
alignment = "soft", feature_map = identity_maps
)
head(alignment_coverage(soft_fit))
