drcme.spca.spca_transform_new_data

drcme.spca.spca_transform_new_data(spca_results, new_data, spca_zht_params, orig_mean, orig_std, pev_threshold=0.01)[source]

Transform and z-score new data with existing loadings

Results from new data are z-scored with original mean and standard deviation so that they are directly comparable to values in spca_results.

Parameters

  • spca_results (dict) – Output of spca_on_all_data() with original loadings to be applied to new_data

  • new_data (dict) – Dictionary of data sets for transformation

  • orig_mean (array) – Mean values of original sPCs before z-scoring

  • orig_std (array) – Standard deviations of sPCs before z-scoring

  • pev_threshold (float, optional) – Minimum adjusted explained variance level (default 0.01) to retain sPCs

Returns

Transformed and z-scored sPC values

Return type

array
