Webb2 okt. 2024 · This article will discuss the following metrics for choosing the ‘best’ linear regression model: R-Squared (R²), Mean Absolute Error (MAE), Mean Squared Error (MSE), Root-Mean Square Error (RMSE), Akaike Information Criterion (AIC), and corrected variants of these that account for bias. A knowledge of linear regression will be assumed. WebbBoth quantify the direction and strength of the relationship between two numeric variables. When the correlation (r) is negative, the regression slope (b) will be negative. When the correlation is positive, the regression slope will be positive. The correlation squared (r2 or R2) has special meaning in simple linear regression.

WebbIts pretty simple from there. So, we know in the slope intercept formula (y=mx+b) we know that m=slope and b=y intercept. So for the equation I gave you m=1/4 and b=2. So, from the y-intercept (which is 2) you move 4 spaces to the right and 1 space up. Hope that helps!:) Comment ( 4 votes) Upvote Downvote Flag more Show more...
