Regression
Solution
In statistics, regression analysis refers to techniques for modeling and analyzing several
variables, when the focus is on the relationship between a dependent variable and one or more
independent variables. More specifically, regression analysis helps us understand how the typical
value of the dependent variable changes when any one of the independent variables is varied,
while the other independent variables are held fixed. Most commonly, regression analysis
estimates the conditional expectation of the dependent variable given the independent variables
— that is, the average value of the dependent variable when the independent variables are held
fixed. Less commonly, the focus is on a quantile, or other location parameter of the conditional
distribution of the dependent variable given the independent variables. In all cases, the
estimation target is a function of the independent variables called the regression function. In
regression analysis, it is also of interest to characterize the variation of the dependent variable
around the regression function, which can be described by a probability distribution.

  • 1. Regression Solution In statistics, regression analysis refers to techniques for modeling and analyzing several variables, when the focus is on the relationship between a dependent variable and one or more independent variables. More specifically, regression analysis helps us understand how the typical value of the dependent variable changes when any one of the independent variables is varied, while the other independent variables are held fixed. Most commonly, regression analysis estimates the conditional expectation of the dependent variable given the independent variables — that is, the average value of the dependent variable when the independent variables are held fixed. Less commonly, the focus is on a quantile, or other location parameter of the conditional distribution of the dependent variable given the independent variables. In all cases, the estimation target is a function of the independent variables called the regression function. In regression analysis, it is also of interest to characterize the variation of the dependent variable around the regression function, which can be described by a probability distribution.
