Description

A regression analysis is a statistical assessment of the association between two variables, one of which is dependent and the other, independent. The dependent variable is y and the independent variable is x. Regression analysis is used to find the relationships between these variables. Variables within a regression analysis can be negatively correlated or positively correlated.

A situation in which one could model a regression analysis could be the association of hours studied and a grade on a test. The independent variable in this situation is the hours studied, and the dependent variable is the grade on the test because the grade is dependentthe hours studied. The amount of hours one studies has a direct impact on a grade on a test. The relationship between hours studied and the grade on the test is positive because the more hours one studies, theoretically, the better their grade should be.

Applications of Regression Analysis
Regression analysis is a statistical concept of estimating or predicting the relationship
between different elements, usually referred to as variables. The predicted variable is the
dependent variable whereas the predictor is referred to as the independent variable. The process
is used in time series modeling, forecasting and defining the cause and effect relationship
between the variables in use. Typically, regression analysis estimates the conditional expectation
of a dependent variable given th...
