CREATE EXTENSION vasco;Usage
vasco: Maximal Information Coefficient (MIC) extension for PostgreSQL
Discover hidden correlations in your data using the Maximal Information Coefficient (MIC) and the MINE family of statistics.
CREATE EXTENSION vasco;Aggregate Functions
| Function | Description |
|---|---|
mic(x, y) | Maximal Information Coefficient – detects any relationship |
mas(x, y) | Maximum Asymmetry Score – deviation from monotonicity |
mev(x, y) | Maximum Edge Value – degree of continuous function sampling |
mcn(x, y) | Minimum Cell Number – complexity of association |
mcn_general(x, y) | MCN with eps = 1 - MIC |
tic(x, y) | Total Information Coefficient |
gmic(x, y) | Generalized Mean Information Coefficient |
Utility Functions
| Function | Description |
|---|---|
vasco_corr_matrix(table_name, output_table) | Compute MIC for all column pairs and store as a correlation matrix table |
Configuration
SET vasco.mic_estimator = 'ApproxMIC'; -- or 'MIC_e'
SET vasco.mine_c = ...;
SET vasco.mine_alpha = ...;Examples
-- Compute MIC between column pairs
SELECT mic(x, cubic), mic(x, periodic), mic(x, rand_y)
FROM vasco_data;
-- 1, 1, 0.15
-- Create a full correlation matrix
SELECT vasco_corr_matrix('my_table', 'mic_my_table');
SELECT * FROM mic_my_table;Last updated on
