v0.1.36

MacroModelling v0.1.36

Diff since v0.1.35

• major improvements of steady state solver:
  • initial steady state guess can be passed on to @parameters
  • auto-tuning of solver parameters (as a last resort to solver for the steady state)
  • additional steady state problem definition where parameters can deviate during optimisation
  • partial symbolic solve of smaller systems of nonlinear equations (<6 equations) if possible
  • fastest (measured by solution time) solver parameters are selected for each model and used for analysis thereafter
• improved printing of model steady state solution
• translate_mod_file now returns output from dynare preprocessor if it fails
• add function to check the residuals of the non stochastic steady state equations and calibration equations for given values (see get_non_stochastic_steady_state_residuals)
• custom rrule for first order solution - speeding up reverse mode autodiff
