Multicollinearity does not reduce the overall predictive power of the model but it can cause the coefficients of the independent variables in the regression equation to change erratically when small changes are introduced to the regression inputs. Multicollinearity can drastically reduce the validity of ...

We now need to tell Excel what we are looking for in the Vlookup wizard. Remember we have created a new column that represents the concatenation of the item name and item size. So we need to find the concatenation of the item and size when we search for the data. To add the concatena...
The output results of the regression tell us how well we can explain the data sample, but cannot give us an accurate measure of how the model will predict a salary increase. To explore this, we should do the following: Obtain a different sample of the payroll (in our case, we could ge...
as multiple regression models are complex and become even more so when there are more variables included in the model or when the amount of data to analyze grows. To run a multiple regression, you will likely need to use specialized statistical software or functions within programs like Excel....
