Csolnp: State space models
Demonstrate how to compute the Fisher information matrix
Don't warn if not all outcomes are represented in the data
Only run continuous check for continuous vars in WLS.
Comment out speed checks for continuous WLS.
Fix quadrature for two-tier models
This bug only affects two-tier models with more than 1 primary
dimension. Bifactor models were unaffected.
A completed version of the 3x3 Hessians for WLS
Added 3x3 hessian computations for covariances, analytic gradients and hessians for univariate normal, and indexing functions for pre-allocating matrices and vectors of results.
