Bases: object

This is Facade Class for scaling process

Methods

__init__(scaling_setting)
fit_transform_all(interim_data_directories, ...)	This function is consisted of these three process.
from_setting(setting)
inverse_transform(dict_data[, ...])
lazy_fit_all(data_directories, *[, ...])
save(output_directory, file_base_name[, ...])	Save Parameters of scaling converters
transform_file(variable_name, file_path[, ...])
transform_interim_all(data_directories, ...)	Apply scaling process to data in interim directory and save results in preprocessed directory.

Parameters:

scaling_setting (PhlowerScalingSetting)

fit_transform_all(interim_data_directories, output_base_directory, decrypt_key=None, encrypt_key=None)

This function is consisted of these three process. - Determine parameters of scalers by reading data files lazily - Transform interim data and save result - Save file of parameters

Return type:

None

Parameters:

• interim_data_directories (list[Path])

• output_base_directory (Path)

• decrypt_key (bytes | None)

• encrypt_key (bytes | None)

save(output_directory, file_base_name, encrypt_key=None)

Save Parameters of scaling converters

Parameters:

• output_directory (Path)

• file_base_name (str)

• encrypt_key (bytes | None)

Return type:

None
