The Advantages of Regression Analysis & Forecasting. A simple explanation of regression and regression analysis. Regression is a description of the relationship between two variables where one variable is dependent on another variable. The predictor variable is called X and is plotted on the x axis of the graph which is the horizontal axis., Regression analysis is an important tool for modelling and analyzing data. Here, we fit a curve / line to the data points, in such a manner that the differences between the distances of data points from the curve or line is minimized. IвЂ™ll explain this in more details in coming sections..

As previously noted, standardized regression weights are flawed measures of importance because of the intercorrelations among the predictors., the sample size is that regression analysis requires at least 20 cases per independent variable in the analysis. Firstly, linear regression needs the relationship between the independent and dependent variables to be linear. It is also important to check for outliers since linear regression is sensitive to outlier effects. The linearity assumption can best be tested with scatter plots, the.

The Simple Linear Regression Model: IMPORTANT: R-Squared measures how well the model fits the data. Values of R-Squared close to 1 fit well. Values of R-Squared close to 0 fit badly. 9 . The Model Utility Test There is one specific Hypothesis test that has a special significance here. The test H0: ОІ1= 0 Vs HA: ОІ1в‰ 0 tests whether the slope of the regression line is non-zero. Why is Regression analysis is the study of how a response variable depends on one or more predictors, This is probably the most important and frequently encountered regression model.
