Calculates the NA rate and MNAR (Missing Not At Random) score for each peptide. MNAR score is based on the relationship between missingness and mean abundance.

Usage

Arguments

data

A data frame with 'peptide' and 'value' columns

Value

A tibble with columns: peptide, na_rate, mnar_score, mean_abundance
