WebbConclusion: It can be seen by using the Naive Bayes modeling, the prediction accuracy results are 72.3% (0.7232337946103423) with the following numbers: It can be said that the accuracy results are quite low with a value of 72.3% because this value when compared to other models is quite far from the accuracy value. 11.

Each element of X will be a date, and the corresponding element of y will be the associated kwh. Once you have that, you will want to use sklearn.linear_model.LinearRegression to do the regression. The documentation is here. Webb5 jan. 2024 · Linear regression is a simple and common type of predictive analysis. Linear regression attempts to model the relationship between two (or more) variables by fitting a straight line to the data. Put simply, linear regression attempts to predict the value of one variable, based on the value of another (or multiple other variables).
