Abstract: |
Five datasets are included here. The largest is the first and last year of production for American car models from 1896 to 2014. This is the dataset to be used with the PyRate program to estimate diversification dynamics. Fields in this dataset include: clade, a unique identifier for the auto manufacturer; species, a unique identifier for the car model; ts, the year of model origination; and te, the year of model extinction. Three covariate datasets are also included: raw GDP from 1896 to 2014, the price of oil (adjusted for inflation) from 1896 to 2014, and the total number of American car models during the same time period. All datasets are scaled so that the most recent time period is 0 (2014). Finally, a dataset that includes the first and last years of production for battery electric and hybrid electric vehicles is also provided, organized in the same structure as the American car models. |
