當只有一個自變數和一個依變數的情形稱為簡單線性回歸(Simple linear regression),超過一個自變數的情形稱為多元回歸(multiple regression)。 數值預測評估方法 對於數值預測的效果評估,「回歸指標」主要是比較真實數值與預測結果,例如預測銷售量為25645,預測為24332,比較兩者差異值1313,即為最簡單的絕對誤差,從此概念延...
## Multiple R-squared: 0.2469, Adjusted R-squared: 0.2287 ## F-statistic: 13.55 on 3 and 124 DF, p-value: 1.056e-07 Note that traditional dummy coding is fine for regression coefficients, but since traditional dummy codes aren’t orthogonal, it messes things up when you’re just trying...
