WebbTo sum up, first we use optimization to search for the values of B0 and B1 that minimize our cost function. This gives us our model: Z = B0 + B1*X Where B0 = 2.5 and B1 = -0.2 (identified via optimization) We can take a look at our slope coefficient, B1, which measure the impact that distance has on my shooting accuracy. We estimated B1 to be -0.2. WebbSimple linear regression is a statistical method that allows us to summarize and study relationships between two continuous (quantitative) variables. This lesson introduces the concept and basic procedures of simple linear regression. We will also learn two measures that describe the strength of the linear association that we find in data.
