LBmizbinsFun: Calculate the bin breaks for the LBmiz method

In andrew-edwards/sizeSpectra: Fitting Size Spectra to Ecological Data Using Maximum Likelihood

Calculate the bin breaks for the LBmiz method

Description

Calculate the bin breaks for the LBmiz (log binning as done by the package mizer), given xmin and xmax (min and max of data) and the number of bins, k. To be minimised by nlm() to calculate beta.

Usage

LBmizbinsFun(beta, xmin, xmax, k)

Arguments

beta	to be calculated, log10(beta) is the constant binwidth on log10 scale. beta is solution to 0 = beta^(k-2) * (2 * beta-1) - xmax/xmin = 2 * beta^(k-1) - beta^(k-2) - xmax/xmin
xmin	minimum of data (lower bound of lowest bin)
xmax	maximum of data (upper bound of highest bin)
k	number of bins

Value

value to be minimised by nlm()
