Can you direct me to or provide an example that shows how to do a multiple linear regression analysis manually ?
I am very familiar with simple linear regression, and can perform a simple linear regression without the use of a statistics package. However I cannot do the same thing for multiple linear regression, and it is not for lack of Google searching. Most sources I have encountered end up with "And then do the multiple regression analysis in Minitab" (although it's definitely possible that some of them actually provided the method and I just didn't understand it)
In case I have the terminology wrong, when I say multiple linear regression, what I mean is 2 or more independent variables, with a single dependent variable. For instance, do a regression analysis to predict a person's heart attack risk based off their age and weight
