Regression Analysis
R egression Analysis is a statistical technique or a tool that has following objectives/benefits. 1.) Regression analysis indicates if the relationship between the variables is statistically significant. 2.) It indicates the relative strength of the independent variables(x) on the dependent variables. In simple terms it helps us to determine which variable is the more important to predict the dependent variable (y) 3.) Make predictions. Suppose we have got a dataset where we have to predict the house price based on few variables such as a size of the house, location of the house, regression analysis will helps us if these variables (location, size) are actually important/significant for predicting the price of the house. It will also tell us which factor/variable is more important in helping us predicting the price or as earlier said the strength of each variable; also regression analysis will also help us to predict the future price of the houses on t
