<B>B>query()<B>B>  Query the value of the object. It will return the undefined value until there’s something to calculate. 
<B>B>insert()<B>B> 
Insert two new new values into the vectors. This function must be given
precisely two arguments and probably shouldn’t be undefined values in most
cases.
# insert a 4 in one vector and a 3 in the other $object_instance>insert( 4, 3 ); 
<B>B>append()<B>B> <B>B>ginsert()<B>B> 
The growing insert inserts new elements, growing the max size of the vector to
accommodate the new elements (if necessary). This function must be given
precisely two arguments and probably shouldn’t be undefined values in most
cases.
# append a 4 in one vector and a 3 in the other $object_instance>ginsert( 4, 3 ); 
<B>B>query_size()<B>B> 
The current size of the vectors — regardless of their max size (as set by
set_size()). This function returns a list, i.e.:
my @s = $obj>query_size; # two values my $s = $obj>query_size; # the right hand value of the list 
<B>B>set_size()<B>B>  Set the maximum size for the underlying Statistics::Basic::Vector objects. This function requires two arguments. 
<B>B>set_vector()<B>B> 
Set the vector objects used to calculate the object’s value. This function
takes two arguments — which can either be arrayrefs or
Statistics::Basic::Vector objects. They must have the same number of
elements.
my $v1 = vector my $v2 = $v1>copy; $example_correlation>set_vector($v1, $v2); 
This class provides overloads. If evaluated as a string, it will attempt to print a pretty value for the object (or n/a, see query() above). the resulting string can be tuned, in terms of precision, see ipres for further information.If evaluated as a number, it will try to return the raw result of query(), possibly turning the resulting undef (if applicable) into a 0 in the process — note that Perl does this 0izing, not the overload.
The eq and == operators are also overloaded, trying to do the right thing. Also see toler for further information.
