The following are a few resources that I find helpful. I hope you do too!
Resources I developed
A guide to data collection and data management practices, intended as a reference for undergraduate and graduate students. I wrote this document in collaboration with Malcolm Augat and Brian Sanderson.
Written by Dr. Dolph Schluter of the University of British Columbia, this website is a fantastic introduction to data analysis in R, with an emphasis on statistical methods used by ecologists and evolutionary biologists.
This website was developed as a companion to “Generalized linear mixed models: a practical guide for ecology and evolution” by BM Bolker et al. 2009 (Trends in Ecology and Evolution 24: 127-135). It is a detailed and practical guide to the challenges encountered using GLMMs with real ecological data, and includes worked examples with datasets and R code.
