Conduct the Analysis Proc Calis PRINT; PRINT adds to the default output the total effects matrix (and some other things)
Linear Equations LINEQS Intent = b1 Attitude + b2 SubNorm + b3 PBC + E1, Intent has paths to it from Attitude, SubNorm, PBC, and E1 (the error term) b1, b2, and b3 are the path coefficients that we want SAS to estimate for us
Linear Equations Behavior = b4 Intent + b5 PBC + E2; Behavior has paths to it from Intent, PBC, and E2. SAS assumes that the exogenous variables (Attitude, SubNorm, and PBC) are correlated.
Linear Equations STD e1-e2 = V1-V2; run; The error terms be estimated as parameters V1 and V2.
The Output You will find much of the same output we found earlier with AMOS, but differently formatted. I shall copy just a bit of it here.
