RGLM predictor thinning. This figure averages the thinning results of 700 applications (predicting 100 gene traits from each of 7 empirical data set). (A) Accuracies decrease as the thinning threshold increases. The black and blue lines represent the median and mean accuracies, respectively. (B) The average fraction of genes left in final models (y-axis) drops quickly as the thinning threshold increases as shown in the black line. The function in Equation 1 approximates the relationship between the two variables as shown in the red line. (C) Number of genes used in prediction for no thinning versus thinning threshold equal to 20. On average, less than 20% of genes remain.
