The authors missed an important reference “Liu, Luo, & Liu, 2014” on the original version of this article. With this, this should be added on text to read:

“We referred to the PGMM model based on the reading development indicators of ECLS-K as guides setting the above residual values (e.g., see Liu et al. 2014; Liu et al. 2016; Kainz and Vernon-Feagans 2007; Tourangeau et al. 2009).”

In reference list, “Liu, Y., Luo, F.,& Liu, H. (2014). Factors of piecewise growth mixture model: distance and pattern. Acta Psychologica Sinica. 46(9). 1400-1412. doi:10.3724/SP.J.1041.2014.01400” should be listed.
