The modeled relationship between tree growth, status, competition and climate in trees from 2000s sites.

Summary of the linear mixed-effects model with the formula RW∼PPTCool + (PPTCool)2+ VPDMJJ + (VPDMJJ)2+ CI + Tree Status + Site + CI:Tree Status + PPTCool:CI + PPTCool:Tree Status + VPDMJJ:CI + VPDMJJ:Tree Status + PPTCool:Site + (PPTCool)2:Site + VPDMJJ:Site + (VPDMJJ)2:Site + CI:Site + Tree Status:Site + PPTCool:CI:Site + PPTCool:Tree Status:Site + VPDMJJ:Tree Status:Site + VPDMJJ:CI:Tree Status, random = (∼1 | TreeID). A correlation term and variance weights were also included in the model in order to account for residual autocorrelation of growth between years and variance heterogeneity of residuals by TreeID and across fitted values [65]. Growth was modeled from 1980, with the end of the modeled period varying depending on the outer growth year of the dead tree in each pair. Model parameters with estimates of (p
