What Is Matthews Correlation Coefficient?
Matthews Correlation Coefficient derives the regression line from mean, standard deviation, and correlation.
Formula
slope = r × σy/σx, intercept = ȳ − slope × x̄Frequently Asked Questions
What is R²?
R-squared measures how much variance in Y is explained by X. 0 to 1; higher means better fit.
