ad2Zipf: partition-adjusted Zipf


ad2Zipf (-h -mW -kX -KY -EZ -H) text.spc

Partition-adjusted extended Zipf's law. Estimates the partition parameter p by minimizing the mean squared error. Estimates Z by requiring that V(N) = E[V(N)]. For a detailed description of the standard lnre output files, see lnreZipf.

input

    text.spc: the frequency spectrum

    text.obs should be available in the working directory

options

    -h: display on-line help

    -mW: number of frequency ranks m in the fit is set to W (default: 15)

    -kX: number of chunks for interpolation is set to X (default: 20)

    -KY: number of chunks for extrapolation is set to Y (default: 20)

    -EZ: extrapolation sample size is set to Z (default: 2N_0)

    -H: input file has no header (default: with header)
