rm_trend
(x, y, dim='time', nan_policy='none')[source]¶ Removes a linear fit from
y
regressed ontox
.Parameters: - y (x,) – Independent and dependent variables used in the linear fit.
- dim (str, optional) – Dimension to apply linear fit over. Defaults to “time”.
- nan_policy (str, optional) –
Policy to use when handling nans. Defaults to “none”.
- ’none’, ‘propagate’: If a NaN exists anywhere on the given dimension,
- return nans for that whole dimension.
- ’raise’: If a NaN exists at all in the datasets, raise an error.
- ’omit’, ‘drop’: If a NaN exists in x or y, drop that index and
- compute the slope without it.
Returns: y
with linear fit removed.Return type: xarray object
