Ok, THERE is your problem. Why do you have separate implementations of all those functions? Does the abs of a time series simply mean the abs of each element of the series? In that case you want just ONE method, something like "map", which applies an arbitrary function to all elements of the series. Then for time series ts, instead of saying ts.abs(), you'd say ts.map(abs) where abs is the existing, built-in absolute value function. You could similarly say ts.map(acos) etc. That gets rid of almost all of those methods. -- http://mail.python.org/mailman/listinfo/python-list
