Probability and band completeness distributions for the sources of the three galaxies (IC 1613, WLM, and Sextans A) with and without missing data. Top: probability distributions of the correct (blue) and incorrect (orange) final classifications for the total sample of stars with known spectral types and with measurements in all bands. We achieved a recovery rate of ∼70%. The vertical dashed lines are the same as those in Fig. 6; the solid lines correspond to the peak of the probability distributions for the current sample. Middle: Distribution of the band completeness, i.e., the fraction of features without missing values. Bottom: probability distributions for all sources, including those without measurements in multiple bands (vertical lines have the same meaning as in the top panel). The success rate of ∼68% is the same as in the top panel, indicating the effectiveness of the iterative imputer for missing data imputation.
