MMMIDataWrapper.to_scaled#

MMMIDataWrapper.to_scaled(var)[fuente]#

Transform variable from original to scaled space.

Handles three scenarios based on input type:

String ending with “_original_scale”: Returns the corresponding base variable from posterior (e.g., «mu_original_scale» → posterior[«mu»]). The base variable is already in scaled space.
String without “_original_scale” suffix: Returns the variable directly from posterior (e.g., «channel_contribution» → posterior[«channel_contribution»]). These variables are already in scaled space, so no transformation is applied.
xr.DataArray: Assumes the data is in original scale and divides by target_scale to convert to scaled space.

Parameters:

varstr or xr.DataArray: One of: - Variable name ending with “_original_scale” (returns base scaled variable) - Variable name in posterior (returns as-is, already scaled) - DataArray in original space (divides by target_scale)

Returns:

xr.DataArray: Variable in scaled space

Raises:

ValueError: If string variable is not found in posterior, or if target_scale is not found in constant_data when scaling a DataArray

Examples

>>> # Get scaled version of original scale variable
>>> scaled = wrapper.to_scaled("mu_original_scale")
>>>
>>> # Get already-scaled variable directly
>>> scaled = wrapper.to_scaled("channel_contribution")
>>>
>>> # Convert DataArray from original to scaled space
>>> original_data = posterior["mu"] * constant_data.target_scale
>>> scaled = wrapper.to_scaled(original_data)
