Calculate distribution overlap by distribution fitting

Calculate distribution overlap by distribution fitting. User need to specify which distribution family to use. This function estimates population distribution from sample distributions. It utilizes fitdist function in fitdistrplus R package.

ovl_distfit(x1, x2, family = c("norm", "lognorm", ...))

Arguments

x1	A numeric vector.
x2	A numeric vector.
family	A string to specify the distribution family.

Value

estimated overlap between two distributions (range: 0 to 1)
