Usage

down.up(data,x,n.rep,h)

Arguments

data

n.rep

A vector consisting of the number of replicate arrays at time points (1, 2,… ,T), where T is the total number of time points.

h

Down-up profile with minimum at h.

Value

logelr

Log-maximum likelihood

mu

A vector containing the estimator of the mean
