### CosmoMC: Fisher Matrix

Posted:

**November 23 2004**Hi,

Does anybody know whether the actual Fisher matrix of the posterior distribution can be calculated using CosmoMC?

Since this distribution is not exactly a multivariate gaussian, its Fisher matrix should be different from the covariance matrix, shouldn't it?

Thanks!
