== Identification ==

=== Local identification ===

 * keyword + option in preprocessor
 * entry function: dynare_identification (move to special directory)
 * polishing
   * change default of prior_mc to 1 => set parameter values at which to check identification: posterior mode, prior mode, posterior mean... (we should probably introduce a syntax that will be reused for stoch_simul after estimation, for the smoother, for forecast after estimation...)
   * add declaration of parameter list (after the list of options, like the list of variables for stoch_simul)
   * rename options_ident.prior_range -> use_prior_shape (+ preprocessor)
   * streamline output
     * rank condition 
     * if not satisfied, why ? 
   * needs documentation + test
 * further developments: 
   * SVD decomposition of Jacobian matrix
   * derivative of Kalman filter for derivative of information matrix
     (also useful for optimization)

=== Global identification ===
 * exploration stage
 * consequences for unicity of steady state
 * provide 2nd derivatives of the static model [[https://www.dynare.org/trac/ticket/127|Ticket #127]]

== Steady State ==
 * check global/local use of M_.params when some parameters are changed in the computation of the steady state (partially done)
 * steady_state_model:
   * explore possibility of providing 1st and 2nd derivatives of analytical steady state with respect to parameters
   * provide for call to fsolve() with Dynare model sub-blocs (equation tag ?) (to be implemented)
   * exceptions (return with penalty, alternative functional forms such as Cobb-Douglas as a degenerate case of CES) for some parameter and endogenous variable values
   * allow # expressions in steady_state_model (derivatives are transparent) 
   * allow for modification of parameters in steady_state_model (! derivatives)
 * STEADY_STATE operator: derivative with respect to parameter is NOT zero  in dynamic model. Derivative of steady state with respect to parameter needs to be provided to dynamic model derivator (current bug, [[https://www.dynare.org/trac/ticket/128|Ticket #128]])
