Reading a linear regression table
WebMay 24, 2024 · Table 1: Simple regression of sales on TV Values for β0 and β1 are 7.03 and 0.047 respectively. Then the relation becomes, Sales = 7.03 + 0.047 * TV. This means if we spend an additional 1000 dollars on TV advertising media it increases the sales of products by 47 units. This gives us how strongly the TV advertising media associated with the sales. WebAn example of what the regression table “should” look like.
