I wonder if her discovery of the P-L (period vs luminosity) relationship (brighter Cepheid stars tend to have longer period) received the same statistical attention. I wonder how statistics was prevailed in astronomy 100 years ago. Hubble’s discovery, farther galaxies recess faster, is accentuated by simple linear regression or least square fitting.
