Hello
I Have a muliple regression:
y=a1*x1+a2*x2+a3*x3+a4*x4+a5 and i want simulate data for Least-Squares Variance component Estimation (LS-VCE). How I can Simulate data for this problem?

Sorry, I'm not familiar with LS-VCE, so I don't really understand what you want. As you probably know, though, the inputs to mvnrnd uniquely determine the joint distribution of the generated random numbers, so I am pretty sure that your only option is to vary those inputs until you get the outputs that you want (cofactors etc).
You can generate very large sample with mvnrnd to get close to the "true" underlying output values, and then generate any desired smaller samples with the same parameters for your simulation.
