Expanding on the penguins multiple linear regression from last week, we will compare different permutations of the model, explore collinearity, and make a finalized table of regression outcome(s).
Data exist in built-in penguins dataset in the palmerpenguins R package.
Data from: Gorman KB, Williams TD, Fraser WR (2014). Ecological sexual dimorphism and environmental variability within a community of Antarctic penguins (genus Pygoscelis). PLoS ONE 9(3):e90081. https://doi.org/10.1371/journal.pone.0090081
In this example, we will ask: is there an association between lizard species and tail breakage? Also includes: wrangling, counts, visualization & communication.
Data are in data/ as 'lizards.csv'
