STATISTICS 1. REGRESSION: 연속된 독립변수와 종속변수의 관계 및 경향성을 찾는 방법 --> Least Squares (오차를 최소화하는 모델 찾기) X: [1, 2, 3, 4, 5] Y: [2, 4, 5, 4, 5] 1. FIND DEVIATION OF X and Y deviation of x = X - x̄ deviation of y = Y - ȳ deviation of x: [-2, -1, 0, 1, 2] deviation of y: [-2, 0, 1, 0, 1] 2. CALCULATE PRODUCT OF DEV deviation of x * deviation of y product of deviations: [4, 0, 0, 0, 2] 3. CALCULATE SQUARED DE..
