GridDB is an open source time series database optimized for IoT and Big Data. GridDB offers speedy ingestion via its NoSQL interface, as well as the standard SQL for querying. Time series functionalities such as data retention, sampling makes it easy to manage sensor data.
Provide for uniform handling of R's different time-based data classes, maximizing native format information preservation and allowing for user level customization and extension, while simplifying cross-class interoperability.
Simplifies conversion of the following formats:
zoo ts timeSeries
... [More] its matrix data.frame What is an xts object? Essentially a zoo object that enforces time-based indexing, AND one that can be extended with arbitrary attributes (source, last update, ...).
With that requirement satisfied methods can be written that can rely on the time indexing. Another useful application is to convert all possible time-based data inputs to an xts object, and then convert back to the original class with nothing more than a call to reclass. [Less]
PyMacLab is the Python Macroeconomics Laboratory which serves the purpose of providing a convenience framework written in form of a Python library with the ability to solve non-linear DSGE models. The library supports solving DSGE models using 1st and 2nd order perturbation methods which are
... [More] computed around the steady state. PyMacLab possesses the added advantage of being equipped with an advanced model file parser module, which automates cumbersome and error-prone linearization by hand. PyMacLab is written entirely in Python, is free and incredibly flexible to use and extend. [Less]
