Figure 4.
The line graph plots E R on the horizontal axis from 0.000 to 0.600 and L R statistics on the vertical axis from 0 to 80. The L R statistic begins around the mid 60s at low E R values and fluctuates near 60 to 67. It then falls sharply around E R 0.14 to about 30, declines further to around 10 near E R 0.19 and briefly reaches approximately 0 near E R 0.20. The statistic then rises to around 20 to 40 between E R 0.21 and 0.28. Around E R 0.29 it jumps sharply above 60 and thereafter fluctuates mostly between about 58 and 66 through E R 0.60, ending near the upper 60s. A horizontal dashed reference line runs near an L R statistic of 7.LR diagram of environmental regulations as threshold variables
