VariableUncertainty.__setitem__

VariableUncertainty.__setitem__(unc_var: str, unc_def: DataArray | Variable | Tuple[List[str], ndarray, dict | None])

Adds defined uncertainty variable to dataset

Parameters:

• unc_var – uncertainty variable name

• unc_def – either xarray DataArray/Variable, or definition through tuple as (dims, data[, attrs]). dims is a list of variable dimension names, data is a numpy array of uncertainty values and attrs is a dictionary of variable attributes. attrs should include an element pdf_shape which defines the uncertainty probability density function form, and err_corr which defines the error-correlation structure of the data. If omitted pdf_shape is assumed Gaussian and the error-correlation is assumed random.

Returns:
