Hello,
I have a file which has a range of date like:
00:00 test
00:01 test2
00:02 test3
00:03 test4
00:04 test5
00:05 test6
Using input (stdin) i would like to parse the data 00:01 to 00:04. The output file should be like this:
00:01 test2
00:02 test3
00:03 test4
00:04 test5

NAME
PDL::Fit::Polynomial - routines for fitting with polynomials
DESCRIPTION
This module contains routines for doing simple polynomial fits to data
SYNOPSIS
$yfit = fitpoly1d $data;
FUNCTIONS
fitpoly1d
Fit 1D polynomials to data using min chi^2 (least squares)
Usage: ($yfit, [$coeffs]) = fitpoly1d [$xdata], $data, $order, [Options...]
Signature: (x(n); y(n); [o]yfit(n); [o]coeffs(order))
Uses a standard matrix inversion method to do a least squares/min chi^2 polynomial fit to data. Order=2 is a linear fit (two parameters).
Returns the fitted data and optionally the coefficients.
One can thread over extra dimensions to do multiple fits (except the order can not be threaded over - i.e. it must be one fixed scalar
number like "4").
The data is normalised internally to avoid overflows (using the mean of the abs value) which are common in large polynomial series but the
returned fit, coeffs are in unnormalised units.
$yfit = fitpoly1d $data,2; # Least-squares line fit
($yfit, $coeffs) = fitpoly1d $x, $y, 4; # Fit a cubic
$fitimage = fitpoly1d $image,3 # Fit a quadratic to each row of an image
$myfit = fitpoly1d $line, 2, {Weights => $w}; # Weighted fit
Options:
Weights Weights to use in fit, e.g. 1/$sigma**2 (default=1)
BUGS
May not work too well for data with large dynamic range.
