gemmr.sample_size.linear_model.get_lm_coefs(model, criterion, target_error, target_power, data_home)¶

Get linear model coefficients.

For default parameters, i.e. if criterion='combined', target_power=0.9 and target_error=0.1, coefficients are read from file '../datasets/sample_size_lm_[model].csv'. Otherwise, they are calculated from outcome datasets.

Parameters:

model (str) – ‘cca’ or ‘pls’
criterion (str) –
Can be:
- 'combined'
- 'power'
- 'association_strength'
- 'weight'
- 'score'
- 'loading'
- 'crossloading'
target_error (float between 0 and 1) – target error level
target_power (float between 0 and 1) – target power level
data_home (None or str) – path where outcome data are stored, None indicates default path

Returns:

intercept (float) – linear model intercept
coefs (np.ndarray) – linear model coefficients
