JointDistribution.enable_FD(epsilon=None)[source]#

Enable finite difference approximation for logd gradient. Note that if enabled, the FD approximation will be used even if the _gradient method is implemented. By default, all parameters will have FD enabled with a step size of 1e-8.

Parameters:

  • epsilon (dict, optional)

  • finite (Dictionary indicating the spacing (step size) to use for)

  • variable. (difference approximation for logd gradient for each)

  • names. (Keys are variable)

  • FD (Values are either a float to enable FD with the given value as the)

  • size (step)

  • for (or None to disable FD for that variable. Default is 1e-8)

  • variables. (all)
