NAME

       odffindbasic - Basic macro removal from OpenOffice.org files

USAGE

       odffindbasic [options] <sourcefile> [<targetfile>]

DESCRIPTION

       A simple command that allows the user to detect, export or remove the Basic modules from a regular OpenOffice.org file.

       Without option, the program displays the number of Basic modules found in the file.

       The 2nd filename is used in combination with the --delete option.

OPTIONS

	       --nocount
		       Prevents the program from displaying the number of Basic
		       modules found.

	       --delete -d
		       If this option is set, the Basic modules are physically
		       deleted. The file manifest is updated accordingly.
		       However, the document content remains unchanged, even if
		       it contains some references to the deleted macros. The
		       code is removed (so the macros are no longer executable).
		       If a target file name is provided as a 2nd argument, the
		       changes are saved in it and the source file remains
		       unchanged.

	       --export -e
		       Exports the macros. Every Basic module is extracted and
		       converted to a flat Basic source file in the current
		       directory. The name of each created file is constructed
		       according to the corresponding path in the ODF file, and
		       its suffix is "bas".

	       --list -l
		       The Basic modules are listed through the standard
		       output.

	       --verbose
		       Some information messages are printed.

Statistics::Basic::Variance(3pm)			User Contributed Perl Documentation			  Statistics::Basic::Variance(3pm)

NAME

       Statistics::Basic::Variance - find the variance of a list

SYNOPSIS

       Invoke it this way:

	   my $variance = variance(1,2,3);

       Or this way:

	   my $v1  = vector(1,2,3);
	   my $var = var($v1);

       And then either query the values or print them like so:

	   print "The variance of $v1: $variance
";
	   my $vq = $var->query;
	   my $v0 = 0+$var;

       Create a 20 point "moving" variance like so:

	   use Statistics::Basic qw(:all nofill);

	   my $sth = $dbh->prepare("select col1 from data where something");
	   my $len = 20;
	   my $var = var()->set_size($len);

	   $sth->execute or die $dbh->errstr;
	   $sth->bind_columns( my $val ) or die $dbh->errstr;

	   while( $sth->fetch ) {
	       $var->insert( $val );
	       if( defined( my $v = $var->query ) ) {
		   print "Variance: $v
";
	       }

	       # This would also work:
	       # print "Variance: $v
" if $var->query_filled;
	   }

METHODS

       new()
	   The constructor takes a list of values, a single array ref, or a single Statistics::Basic::Vector as arguments.  It returns a
	   Statistics::Basic::Variance object.

	   Note: normally you'd use the mean() constructor, rather than building these by hand using "new()".

       query_mean()
	   Returns the Statistics::Basic::Mean object used in the variance computation.

       _OVB::import()
	   This module also inherits all the overloads and methods from Statistics::Basic::_OneVectorBase.

       I am using this software in my own projects...  If you find bugs, please please please let me know. :) Actually, let me know if you find it
       handy at all.  Half the fun of releasing this stuff is knowing that people use it.

OVERLOADS

       This object is overloaded.  It tries to return an appropriate string for the calculation or the value of the computation in numeric
       context.

       In boolean context, this object is always true (even when empty).
