Extended Data Fig. 8: Results of difference-in-differences (DID) analysis when using absolute yield (t/ha) rather than log-transformed yield.
From: The mixed effects of recent cover crop adoption on US cropland productivity
Results shown in Fig. 3 of the main paper are based on a model using log yield. Here, corn and soy results are shown separately due to differences in absolute yield scales (average yields in our sample are 10.9 t/ha for corn and 3.3 t/ha for soy). Values are shown for the pooled sample (a), individual years (b), and individual states (c). Data are presented as point estimates (means) ± 95% confidence intervals, based on standard errors clustered at the state level.
