The April Eco-Stats Lab (Friday 24th, 2pm, Bioscience level 6) will be on zero inflated data in ecology.
It's very common for ecological data to contain many zeros. To account for this we may need to:
1. Use zero inflated regression models
2. Do absolutely nothing (i.e. fit standard glm's)
In this lab we'll talk about why many zeros may occur in ecology, and the appropriate ways to account for them in your analysis.We will mostly use the pscl package in R.
