Statistics::Basic::_OnUsertContributed PerStatistics::Basic::_OneVectorBase(3)NAMEStatistics::Basic::_OneVectorBase - base class objects like Mean
METHODSquery()
Query the value of the object. It will return the undefined value
until there's something to calculate (or until the vector is full
when nofill is in effect).
insert()
Insert new values into the vector.
$object_instance->insert( 4, 3 ); # insert a 3 and a 4
This function returns the object itself, for chaining purposes.
append()ginsert()
The growing insert inserts new elements, growing the max size of
the vector to accommodate the new elements (if necessary).
$object_instance->ginsert( 4, 3 ); # append a 3 and a 4
This function returns the object itself, for chaining purposes.
query_size()
The current size of the vector -- regardless of its max size (as
set by "set_size()").
query_vector()
Returns the Statistics::Basic::Vector object used by the
computational object.
set_size()
Set the maximum size for the underlying Statistics::Basic::Vector
object. This function requires one arguments.
Unless nofill is set, the vector will be filled with 0s (assuming
the vector wouldn't otherwise be full) on the oldest side of the
vector (so an insert will push off one of the filled-zeros).
This function returns the object itself, for chaining purposes.
set_vector()
Given a vector or array ref, this will set the contents (and size)
of the vector used for the object computations.
This function returns the object itself, for chaining purposes.
OVERLOADS
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 0-izing, not the
overload.
The "eq" and "==" operators are also overloaded, trying to do the right
thing. Also see toler for further information.
