calcZhang2019 returns different age estimates compared to Zhang's 2019 predictor #9
Description
According to the provided age predictor by Zhang, Q. et al. (2019), data scaling occurs on the entire dataset before identifying common clock CpGs. However, in this approach, common CpGs are selected first and then the data is scaled. As a result, the age estimates returned by calcZhang2019 are different from those returned by Zhang's 2019 predictor.
