Coefficient Shrinkage with Increasing Lambda. The Y axis represents the value of the coefficients. The X axis represents values of lambda, where a higher value indicates a greater penalty (i.e., greater shrinkage). As lambda increases (i.e., from left to right on the X axis), the value of the coefficients shrink towards zero. The coefficient for Average Time Walking/Day is shrunk to zero first, followed by Peak 30, Fragmentation Index, Average Number of Short Bouts, Average Steps/Day, Percent Sedentary Time, Average Number of Bouts/Day, Average Number of Long Bouts, Average Number of Long Sedentary Bouts, and finally Average Bout Cadence. At a lambda value of 0.03, only Average Bout Cadence and Average Number of Long Sedentary Bouts remained in the model
