My initial thought was that Cov(B1,B2)=0, but this cannot be true or the variance estimates would depend on how you set up the design matrix (the factor symbolized by 0,0 would always have a higher SD).

Please help me find the covariance of the parameter estimates.

Thank you in advance,

Garrett Fox
