Compute the Gini coefficient
...is my data set:
Number of parasites per host:
parasites = c(0,1,2,3,4,5,6,7,8,9,10)
Number of hosts associated with each number of parasites given above:
hosts = c(18,20,28,19,16,10,3,1,0,0,0)
To represent the Lorenz curve:
I manually calculated the cumulative percentage of parasites and hosts:
cumul_parasites <- cumsum(parasites)/max(cumsum(parasites))
cumul_hosts <- cumsum(hosts)/max(cumsum(hosts))
plot(cumul_hosts, cumul_parasites, type= "l")
>From this Lorenz curve, how can I calculate the Gini coefficient with the function "gini" in R (package reldist) given that the...
