cell.length: Example of increment core data

In fiberLD: Fiber Length Determination

Example of increment core data

Description

Simulated data of cell lengths of both cut and uncut fines and fibres from an increment core (as measured by means of an optical fiber abalyzer). The data were simulated from a censored version of a mixture of the fine and fiber length distributions under the assumption that the true lengths of those cells (fines and fibers) that at least partially appear in the increment core follow generalized gamma distributions. Useful for illustrating the use of fled().

Usage

data(cell.length)

Format

cell.length is a vector of 3000 cell lengths simulated from the density

dx.mixture(x, par, r=6, model="ggamma") with parameters

par=c(.32,0.001, 0.276, 5.02, 2.31, 3.41, 1.69).
