Hypothesis Tests in Multiple Regression Analysis
Multiple regression is a statistical analysis offered by GraphPad InStat, but not GraphPad Prism. Multiple regression fits a model to predict a dependent (Y) variable from two or more independent (X) variables: If the model fits the data well, the overall R2 value will be high, and the co...
Learn, step-by-step with screenshots, how to run a multiple regression analysis in Stata including learning about the assumptions and how to interpret the output.
Multicollinearity occurs when the multiple linear regression analysis includes several variables that are significantly correlated not only with the dependent variable but also to each other. Multicollinearity makes some of the significant variables unde
Unlike simple regression in multiple regression analysis, the coefficients indicate the change in dependent variables assuming the values of the other variables are constant.The test of statistical significance is called F-test. The F-test is useful as it measures the statistical significance of the ...

When the number of independent variables is two or more while doing linear regression, it is called multiple linear regression analysis. The equation for calculating multiple regression analysis is as follows. y=b+b1X1+b2X2+...bnXn Where Y is the dependent variable b is the intercept X1 and...

The last table is the most important one for our logistic regression analysis. It shows the regression function -1.898 + .148*x1 – .022*x2 – .047*x3 – .052*x4 + .011*x5. The table also includes the test of significance for each of the coefficients in the logis...
