WebbSimple linear regression draws the relationship between a dependent and an independent variable. ... In the above equation, the slope is represented by “b”. And the linear regression equation for our example turned out as follows: Y= 612.77 – 19.622x. ... In addition to linear regression, Excel offers other forecasting functions too. Webb24 maj 2024 · With a simple calculation, we can find the value of β0 and β1 for minimum RSS value. With the stats model library in python, we can find out the coefficients, 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.
