The confusion matrix is used to check discrete results, but Linear Regression model returns predicted result as a continuous values. That is why you get the error: your dv_test data likely is integer, but y_pred is float.

WebJan 5, 2024 · Put simply, linear regression attempts to predict the value of one variable, based on the value of another (or multiple other variables). You may recall from high-school math that the equation for a linear relationship is: y = m (x) + b. In machine learning, m is often referred to as the weight of a relationship and b is referred to as the bias. WebApr 16, 2024 · The best way to take a look at a regression data is by plotting the predicted values against the real values in the holdout set.
