Calculate Association Metrics

Description

Helper function that computes various association metrics for bigrams based on their probability distributions. Supports PMI (Pointwise Mutual Information), Dice's Coefficient, and G-score calculations.

Usage

calculate_metrics(bigram_probs, association)

Arguments

bigram_probs	A data frame containing bigram probability data with columns: p_xy Joint probability of bigram p_x Marginal probability of first token p_y Marginal probability of second token
association	Character vector specifying which metrics to calculate

Value

A data frame containing the original probability columns plus requested association metrics:

• pmi: Pointwise Mutual Information

• dice_coeff: Dice's Coefficient

• g_score: G-score
