The relevant article is found here. In it, Reilly says he built a regression model with covariates as population [number], population density, median income, median age, diversity (measured as the percentage of minorities in a population), and the state’s Covid-19 response strategy (0 = lockdown, 1 = social distancing). #import data library(hav...

Operative Technique Sum of all data in operative technique header is 176. There are four treatments – Open, Laproscopic, lap to open, and Robotic. We want to compare the efficacy of the treatments to each other. In otherwords, we need to do 4 permutation tests where we compare a treatment to its complement. For example, we want to compare the e...
