effDisc_dks function

Discrete Effectiveness as Discrete Kernel-smoothed Distribution.

Fits a Beta-Binomial distribution, to the given sample of scores and support points.

effDisc_dks(x, support, mult = 1)

Arguments

• x: a sample of effectiveness scores between 0 and 1.
• support: the support of the distribution.
• mult: a constant to multiply the initially selected bandwidth.

Returns

an object of class eff.disc.dks, which inherits from eff.disc.

Examples

e <- effDisc_dks(web2010p20[,1], seq(0,1,.05))
c(e$mean, e$var)
plot(e, plot.data = TRUE)
e2 <- effDisc_dks(web2010p20[,1], seq(0,1,.05), mult = 2)
c(e2$mean, e2$var)
plot(e2, plot.data = TRUE)
