Ive generated a multiple regression equation using a tool i got online. It takes a list of dependent variables and a few independant variables and gives me a multiple regression equation. The equation is trying to predict defects in a software program. The dependant variables is defect count
the equation i got is
0.32*Avg analysis hr +-0.12*Avg. Dev hrs + 0.00*Budget +-0.19*Duration + 19.40 (+/- 21.56)
These independant variables are project details.
What im trying to do is put one of the projects details back into the equation and get a value for defects.
My problem is that when i put these values in (to test the equation) i get a value which is no where near the actual defects that that project had. even though this project was used in the actual making of the equation.
The R squared of this equation is 91%
Standard error is 21.56
