File List model_code.txt (MD5: dea33b021e62455deada302e8e52145f) Description Daily survival model to estimate the effects of daily weather (and any other covariates of interest) on phenology These data are inputs to the model: events[d,s,y] = {0,1} whether the phenological event was observed on a given day <i>d</i>, at site <i>s</i>, in year <i>y</i>. temp.cum[s,d,y] = cumulative temperature on a given day <i>d</i>, at site <i>s</i>, in year <i>y</i>. precip7[s,d,y] = the amount of precipitation on the previous 7 days for a given day <i>d</i>, at site <i>s</i>, in year <i>y</i>. frost7[s,d,y] = the number of frost events in the previous week for a given day <i>d</i>, at site <i>s</i>, in year <i>y</i>. N.sites = number of sites N.years.sites[s] = number of years of data at each site
