Hi everybody,
it's a technical question .
i have a matrix with 30 columns and 40000 rows, i start my program and i found this error:
"error in solve.default(sBB + Z[,,i] %*% Gamma %*% t(Z[,,i])):
system is computationally singular: reciprocal condition number = 7.6377e-018 "
is it R limit?
Well, if the system is computationally (=almost) singular, so it is very dangeraous to do any computations: your solution can be ways off. You are protected against interpreting unsensible results.

thanks a lot.
