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.
WebbRegression meaning we predict a numerical value, instead of a “ class”. Implementing this algorithm, we fit a line using “least squares”, where we try to minimize the squared distances between the data-points and our line. In its simplest form, we start by drawing any line through our data.
