Testing ProblemsThe purpose of this report is to describe a process for creating unique multiple linear regression problems for each student. Three formulas were utilized to define intercorrelations between variables. A computer program was written based upon these mathematical relationships. To test ...
The general linear regression model takes the form of , with the mean value of y given as , where: y is the random response variable and μy is the mean value of y, β0, β1, β2, and βk are the parameters to be estimated based on the sample data, x1, x2,…, xk are...

which means that is doesn't systematically increase or decrease with changes in the value of independent variable(s). While this is a violation of the equal variance assumption, it usuallycauses no major problems with the regression.
For problems with more than two explanatory variables, determining the coefficients of the multiple linear regression model using the analytical equations could be tedious. In practice, statistical software is the method of choice to obtain the model coefficients and the coefficient of determination (R...

the discussion on specific methods to solve problems related to cascade errors is still lacking. In fact, the experiments conducted by the past studies were not specifically geared towards proving the ability of GRN prediction methods in avoiding the occurrences of cascade errors. Hence, this researc...
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...
