Hi Pedro, I have encountered similar situations in a number of areas. Great care is taken to record significant events of low probability, but not the non-occurrence of those events. Sometimes this is due to a problem with the definition of non-occurrence. To use your example, how close does an

[R] Account for a factor variability in a logistic GLMM in lme4

2018-09-03 Thread Pedro Vaz
We did a field study in which we tried to understand which factors significantly explain the probability of a group of animals (5 species in total) crossing through 30 wildlife road-crossing structures. The response variable is binomial (yes=crossed; no = did not cross) and was recorded by animal
