require that there is no correlation between the independent variables, that is, there is no multiple collinearity. However, there is no relevant two variables that are not present, so the conditions are relaxed to be acceptable as long as they are not strongly correlated.Multiple linear regression in the process of SPSS and simple linear regression, just the content of a few more, and because of the more information, it is recommended to set the ana

SPSS data Analysis-Nonlinear regression

The first satisfying condition of linear regression is the linear relationship between the dependent variable and the independent variable, and then the fitting method is based on it, but if the dependent variable and the independent variable are nonlinear, then the nonlinear regression is needed to analyze it.There are two processes that can be called in the nonlinear regression of SPSS, one is analysis-regression-curve estimation, the other is analy

SPSS data Analysis-least one multiplication

Linear regression is most commonly used as a fitting method with least squares, but the method is more susceptible to strong influence points, so when we fit the linear regression model, we also take the strong influence point as the condition to be considered. For strong-impact points, a more robust fit method is needed in cases where it cannot be corrected or deleted, and the least-squares method is the solution to such problems.The least square method is due to the residual sum of squares, an
