In a linear regression what is b
WebMar 12, 2024 · We are looking to build a generalized model in the form of y=mx+b, where b is the intercept and m is the slope of the line. Because we often don’t have enough information or data to know the exact equation that exists in the wild, we have to build this equation by generating estimates for both the slope and the intercept. WebJul 19, 2024 · Linear Regression is a statistical supervised learning technique to predict the quantitative variable by forming a linear relationship with one or more independent features. It helps determine:...
