Linear regression in data analytics
NettetLinear regression fits a straight line or surface that minimizes the discrepancies between predicted and actual output values. There are simple linear regression calculators that use a “least squares” method to discover the best-fit line for a set of paired data. You … NettetAs very few data points will be around the predicted Regression Line . Thus here Polynomial Regression comes into play.
