A function to determine the curve shape of a binomial probability

Source: R/curve.shape.r

Adapted from Lester Yuan's code. Used in taxon.response.sort().

curve.shape(mnr, ubnd, lbnd)

Arguments

mnr

mean predicted probability
ubnd

upper boundary of mean predicted probability
lbnd

lower boundary of mean predicted probability

Value

returns one of "Unimodal", "Increasing", "Decreasing", "Concave up", or NA.

Examples

mean.resp <- 1:1000
up.bound <- mean.resp+1
low.bound <- mean.resp-1
curve.shape(mean.resp, up.bound,low.bound)
#> [1] "Increasing"
