Lisa I know particularly where Makerere university is, lived in Kampala for any 12 months. Can’t bear in mind my econ degree- Imagine it was minitab, but then in EPI we acquired both of those SPSS and SAS in the College
Karen Within the X matrix, Just about every column is the value in the X which is multiplied by that regression coefficient.

So, the intercept may be described as a single level of X1, X2 = mean, and X3 = mean. And I can see that there's a 3-way conversation during which for one standard of X1 (relative for the intercept as defined above), as X2 goes up and X3 goes up by one device, I want to adjust the estimate for the simple impact of that volume of X1 by some amount of money.
