mescla.reactions.residuals.classify_source_sink

mescla.reactions.residuals.classify_source_sink(result, observed, threshold=0.1, alpha=0.05)[source]

Label each species conservative, source or sink.

Parameters:

  • threshold (float, default 0.10) – Relative departure below which a species is called conservative, whatever its p-value. With many samples a 1% departure becomes statistically significant while remaining chemically meaningless, so significance alone is not enough.

  • alpha (float, default 0.05) – Significance level for the paired t-test.

  • result (MixingResult)

  • observed (Any)

Returns:

DataFrame – The comparison table plus behaviour ("conservative", "source" or "sink") and likely_process drawn from PROCESS_HINTS.

Return type:

pd.DataFrame
