What's new in Cronos 2.03
Mar 17, 2010
- This release includes minor bug-fixes, minor GUI updates, some speed improvements, and support for ARMAX (ARMA with exogenous input) models.
- There is also a new class of object, a "data source". For now the only source is a link to a .csv or .tsv file. But in theory this source could be connected to a variety of different sources: internet pages, broker APIs, databases, etc.
- The User's Guide has been updated a little (thanks to asafarim for feedback in reviewing the last version), although it still has a way to go, and needs to be connected to the help menu somehow.
New in Cronos 2.02 (Jul 20, 2009)
- This release includes a range of bug-fixes and a number of enhancements to the GUI, including the following.
- (1) You can right-click on a node to assign it a comment. The comment appears as a tool-tip when you move the mouse over the node.
- (2) Ctrl-C and Ctrl-V can be used to copy and paste nodes. Unlike in the previous version, a node can be pasted between two different instances of the running application.
- (3) The maximized (or not) state of the application is saved when you exit and restored the next time you run the application.
- The plugin-framework can now be used. To test this, go to Settings->Load Plugin and load "ExamplePlugin.dll". An additional "Adaptive AR" model will be added to the model menu.
- Programmers can add their own custom models and/or transforms. Development documentation on this will be coming later, but for now, you can study the ExamplePlugin project in the source.
New in Cronos 2.01 (Jul 12, 2009)
- This release includes vector autoregressive model support (fitting by Yule-Walker, not MLE). It also includes other minor fixes, as well as additional transformations, including one that computes Bollinger bands.
New in Cronos Stable (Jul 9, 2009)
- This version of this time series analysis package has been tested for a while now (thanks especially to my students in the CMU MSCF program) and although not totally bug-free, is fairly stable.
- Forecasting structure has been finalized, and the GUI has improved substantially (with mouse wheel zoom and scrolling in the workspace) since the beta releases.
- To differentiate it from the older version of the software, this initial release is version 2.00.
New in Cronos 0.999 Beta (Jul 5, 2009)
- This version of this time series analysis package uses standard Windows buttons in the workspace, includes linear filtering transforms, and has a number of small bug-fixes.
New in Cronos 0.998 Beta (Jul 4, 2009)
- This version of this time series analysis package includes a visualization node for residual analysis (which shows a normal QQ plot and computes some iid test p-values), as well as other minor fixes and enhancements.
New in Cronos 0.997 Beta (Jul 3, 2009)
- This version of this time series analysis package fixes the toolstrip positioning problem and allows for date/time ranges to be specified when simulating from models.
New in Cronos 0.996 Beta (Jun 30, 2009)
- This version of this time series analysis package includes a number of improvements over the previous one.
- Plot export is now properly supported (right-click on plots). Plots can be copied as bitmaps to the clipboard or exported to pdf files.
- A new plugin framework is included so that users can develop their own transforms and/or models. (No plugins yet, but future releases will include sample plugin code.)
- A simple toolbar is now included. For now it includes differencing and integrating transforms, but it can easily be expanded in future releases.
New in Cronos 0.984 Beta (Jun 29, 2009)
- This is the latest preliminary (beta) release of this time series analysis package.
- ARMA and GARCH models are supported, and there is a range of data transformations available.
- The release consists of a windows installation package and a user's guide in pdf format.
- Main changes from 0.982: couple of new transformations added, bugs fixed, maximum likelihood fitting shows a progress bar.
