NAME

Text::NumericData::Stat - generate statistics for Text::NumericData::File objects

SYNOPSIS

        use Text::NumericData::Stat;

        # read some input file (all columns numeric)
        my $file = new Text::NumericData::File(\%config,$filename);

        my $statfile = Text::NumericData::Stat::generate($file);

        # use individual values
        print "mean value of first column: ",$statfile->{data}[0][0],"\n";
        print "standard error of first column: ",$statfile->{data}[0][1],"\n";  
        # or just write it down
        $statfile->Write($outfilename);

        # one can also restrict statistics to certain columns
        # indices zero-based
        $statfile = Text::NumericData::Stat::generate($file, [0, 3, 8]);

DESCRIPTION

This takes a Text::NumericData::File as input and computes statistics for each column, producing a new Text::NumericData::File with each data set representing a column of the input file, the columns of the new file containing the respective mean and standard deviation values (or more statistic measures in future).
