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. Uwe Ligges
thanks a lot. Jonathan Charrier
