  1. The Pearson's correlation coefficients are calculated between F1 score and the two likelihood functions, the sum of the similarity scores (LS) and the product of the similarity scores (LP), for each method of the proposed peak alignment algorithms, SWRM, SWRE, and SWRME, on two homogeneous data and one heterogeneous data which were generated from a mixture of compound standards and the spiked-in data. The correlations in bold and italic are statistically significant at 5% level (p-value < 0.05) and the values in parentheses are p-value.
