  • The dependent variable is the cumulative infection rate (Y) in each of the 298 slum zones in Delhi, India. The variable ‘average degree,’ denoted by x1, refers to the average number of contacts per individual within the slum zone and the variable ‘average household size,’ denoted by x2, refers to the average household size in the slum zone. b0 refers to the intercept of the fitted regression model, and b1 and b2 are the coefficients of x1 and x2, respectively.
