Summed Coefficients are the sum of the absolute values of LARS regression coefficients in each model.

Proportion Occurrence denotes the proportion of 21 models where a regression coefficient ≠ 0.

Total Score is the sum of ‘summed coefficients’ and ‘proportion occurrence’.

^*Values calculated from seven models, not 21, as this covariate was only measured at Edgewater Beach.
