Stéphane Adjemian (Charybdis) 6efe62a3b2 Transposed the definition of the innovations in (stochastic) extended path routine, so that, for a given state of the random number generator, stochastic simulations obtained with extended_path and stoch_simul commands consider the same innovations (when the number of shocks is greater than one). Otherwise the stochastic simulations cannot be compared. 2013-12-17 22:49:37 +01:00

Stéphane Adjemian (Charybdis) 6328a44f33 Streamlined extended paths routines.
*  Removed the  necessity (for  the  user) to  run stoch_simul  bebore
executing the exetended path routine (when options_.init>0).

*  The  value  of  options_.ep.init  defines the  mix  (used  for  the
initialization of  the perfect foresight solver)  between the previous
perfect foresight  solution and  the path obtained  with an  order one
perturbation approach.

* Removed timing related statements.

*  Changed homotopy set-up  for stochastic  extended path:  add future
multivariate innovations one by one.

* Endogeneously increase step_length in the homotopy routine.

* Removed homotopy_2 related code.

Stéphane Adjemian (Charybdis) ecfc5bbbc9 Removed nonsensic options (for the evaluation of the expectations). 2011-12-26 11:53:08 +01:00
Stéphane Adjemian (Charybdis) e2f69ab4fc Added arbitrary order of approximation for the Stochastic Extended Path approach.
Default is that we only consider shocks in t+1 to approximate the expectations. If
options_.ep.stochastic.order is set to s>1, shocks in t+1, t+2, ..., t+s are
considered. Obviously the (tensorial) tree of future shocks is growing
exponentially.

Other numerical rules of integration have to be added...
