Michel Juillard 39cc313964 removed changes linked with transforming variables to avoid log or 
power of negative numbers
 2013-04-09 16:35:57 +02:00
Sébastien Villemot a0b7178962 Automatic detrending engine can now handle models written in logs (ref. #309) 
- new command `log_trend_var'
 - new option `log_deflator' to `var' command

Michel Juillard 539bf0ca69 finishing implementation of optional transformation of log and non 
integer power arguments   to insure that they are positive
 2012-05-26 20:53:48 +02:00
Michel Juillard c6495dfc9d first implementation of transform_logpow. It creates too many auxilary 
variables and probably violates Jensen inequality in some cases.

Michel Juillard 629673199e starting implementation of transformed variables to replace arguments 
of log and pow functions so as to insure non-negative arguments

 2010-09-20 17:04:38 +02:00
Ferhat Mihoubi 60f7678669 - Substitutes lead for exogenous and endogenous variables in the deterministic case: direct substitution of the variables even in non-linear expressions 2010-09-17 12:17:09 +02:00
Ferhat Mihoubi 0a3c8a4b0c - compute the jacobian matrix for exogenous, det_exogenous and previous blocks endogenous 
- preprocessor provides informations about the dynamic structure of each block
- extends the algorithms available with bytecode: stack_solve_algo = 1, 2, 3 and 4 is compatible the bytecode. Speed and memory requirement are improved with stack_solve_algo = 1 or 4 for large scale models.
- bytecode can be used to evaluate a model

sebastien 76e691c651 preprocessor: 
* fixed a bug with EXPECTATION operator: now handle model local variables
* substitute EXPECTATION operator even in deterministic models (for avoiding crashes, even if use of this operator doesn't make sense there)
* forbid the use of EXPECTATION and STEADY_STEATE outside model block
* minor implementation changes in EXPECTATION and STEADY_STATE operators

reference manual:
* documented EXPECTATION and STEADY_STATE operators
* added a note in write_latex_{static,dynamic}_model commands documentation about auxiliary variables and other model transformations
