Nettet26. okt. 2024 · Simple linear regression is a technique that we can use to understand the relationship between a single explanatory variable and a single response variable. This … Nettet10. jan. 2024 · Simple linear regression is an approach for predicting a response using a single feature. It is assumed that the two variables are linearly related. Hence, we try to find a linear function that predicts the response value (y) as accurately as possible as a function of the feature or independent variable (x).

We typically want to know if the slope coefficient, b 1, is statistically significant. To determine if b 1 is statistically significant, we can perform a t-test with the following test statistic: t = b 1 / se(b 1) where:
