gemmr.sample_size.linear_model._save_linear_model

gemmr.sample_size.linear_model._save_linear_model(model, data_home=None, verbose=False)

Save linear model.

Creates csv files with parameters for

  • criterion == ‘combined’

  • target_power == 0.9

  • target_error == 0.1

When these parameters are given in cca_sample_size() or pls_sample_size(), then linear model coefficients are read from file “gemmr.datasets.sample_size_lm_[model].csv”. This allows to quickly calculate sample sizes without having the complete outcome data available.

For internal use.

Parameters:

  • model (str) – ‘cca’ or ‘pls’

  • data_home (None or str) – if str indicates path where outcome data are stored, None is interpreted as default path

  • verbose (bool) – if True intercept and coefficients of fitted linear model are printed to stdout
