next

Causes the process to advance through the number of steps and return the state associated with the last step taken. This allows the sampling to skip the number of steps between returned observations. If the sampler is not initialized, it will be initialized. If it has already been initialized, it will not be re-initialized. This is a convenience method which repeatedly calls the function next() for the specified number of steps.

Moves the process one step. If the sampler is not initialized, it will be initialized. If it has already been initialized, it will not be re-initialized.
