NAME
gbmodes - Analyze multimodality in univariate data
SYNOPSIS
gbmodes [ options ]
DESCRIPTION
Multimodality analysis via kernel density estimation. Compute the maximal kernel bandwidth h_c(M) for which #(modes in the estimated density)>M.The significance of h_c is computed via smoothed bootstrap. Read data from std. input. Print the couple h_c p(h_c) and the modal values (set with -O ).
OPTIONS
|
-n |
number of equispaced points where the density is computed (default 100) |
||
|
-m |
number of modes (default 1) |
||
|
-r |
search range for modes; comma separated couple ’data_min,data_max’ |
||
|
-s |
scale the search range to [min*s+(1-s)*Max,Max*s+(1-s)*min] (default 1) |
||
|
-e |
relative tolerance on h_c value (default 1e-6) |
||
|
-S |
significance level (for Hall-York correction) (default .05) |
||
|
-t |
number of bootstrap trials used for significance computation (default 1000) |
||
|
-R |
RNG seed for bootstrap trials (default 0) |
||
|
-K |
choose the kernel to use: 0 Gaussian or 1 Laplacian (default 0) |
||
|
-v |
verbose mode (more verbose if provided 2 times) |
||
|
-O |
output type (default 0) |
||
|
0 |
h_c p(h_c) [modes locations] |
||
|
1 |
h_c [modes locations and heights] |
||
|
-F |
specify the input fields separators (default " \t") |
||
|
-h |
