  1. PGS polygenic score, SD standard deviation, AD Anno Domini, PCC Pearson correlation coefficient, SD equation for PCC = sqrt [(1 - PCC²) / (N - 2)].
  2. a Number of samples with a value greater than 0.05 from take the absolute value after subtracting the actual height from the predicted height and then divided by the actual height.
