residfit function

Plot residuals against fitted values

Plots randomized-quantile residuals for binomial N-mixture models against fitted values.

residfit(umFit, type = "marginal", ...)

Arguments

• umFit: An object from a model fitted using pcount .
• type: The type of randomized quantile residual to plot. One of 'marginal', 'site-sum' or 'observation'.
• ...: Plot arguments.

Examples

library(unmarked)
umf = unmarkedFramePCount(y = shoveler$y, obsCovs = shoveler$obs, siteCovs = shoveler$site)
fmP = pcount(~scale(date) + scale(reedcover) ~ scale(log(water)) + scale(latitude), 
      data = umf, K = 80)
residfit(fmP, "marginal")
residfit(fmP, "site-sum")
residfit(fmP, "observation")
