Linear Regression Polynomial Regression red curve fits the data better than the green curve= situations where the relation. between the dependent and independent variable seems to be non-linear we can deploy Polynomial Regression Models. Quantile (percentile) Regression • generally use ...
Regression Analysis • Our objective is to analyze the relationship between interval variables; • Regression analysis is used to predict the value of one variable (the dependent variable) on the basis of other variables (the independent variables). • Dependent variable: ...
