Cox lasso variable selection for recipients ages 50 and under.
The top row represents the number of non-zero coefficients per Lasso penalty value, lambda. The vertical line L0 corresponds to the optimal penalty, which minimizes the PLD. The line Lσ corresponds to the largest penalty value corresponding to the PLD values within one standard deviation of the minimum PLD.
