I want to create an ANOVA table to check for lack of fit sum of squares in a linear regression problem where the yield,y can be approximated as Y=b0 + b1x1 +b2x2
X1=[45 55 45 55 50 50 50]; X2=[ 90 90 110 110 100 100 100]; Y=[90 59 78 67 68 66 69];
The lack of fit sum of squares were calculated as 0.83 while the pure error was calculated as 4.62. I am using Matlab 2007b
