openghg_inversions.hbmcmc.components

Classes and functions to making self-contained parts of the RHIME model.

openghg_inversions.hbmcmc.components.make_offset(site_indicator: ndarray, prior_args: dict, name: str = 'offset', output_dim: str = 'nmeasure', drop_first: bool = False, offset_freq: str | None = None, offset_freq_indicator: str | None = None) → TensorVariable

Create an offset inside a PyMC model.

Note: this must be called from inside a PyMC model context.

Parameters:

• site_indicator – array with same length as obs, with integers to indicator which site an observation belongs to

• prior_args – dict of prior args for offset prior

• name – name for offset in PyMC model

• output_dim – name of dimension for output

• drop_first – if True, set first site’s offset to zero

• offset_freq – frequency for which to solve for the offset (e.g. “M”). Not used.

• offset_freq_indicator – array of period indicators for each measurement

Returns:

TensorVariable containing offset vector (to add to modelled observations).
