My professor isn't very clear to say the least Is there way to calculate all of the inputs needed for linear regression hand calculations Like x^2, y^2, sxy, syy, etc I googled it and it didn't come up with anything I'm using sas university edition What is the meaning of the symbols $s_{xx}$ and $s_{xy}$ in simple linear regression
I know the formula but what is the meaning of those symbols? In a simple linear regression model, i have only sxy and syy data with me How shall i derive sxx, linking sxy and syy based on first principles I know the formulas separately I want to find sxx,.

The intersection of the angle bisectors of ade a d e and bed b e d is in point f f If f f belongs to the edge ab a b, prove that it's the midpoint of the edge ab a b I think that we have to prove that af a f is an altitude of the triangle abc a b c (since it's an isosceles triangle)
