PickStock

PickStock (copyright 2003, Bell Software and Services, Inc.) uses principal components analysis to search out potentially underpriced stocks by analyzing a user-supplied database of historical stock prices. The program is believed to be an implementation of what is known in the financial market modeling community as 'arbitrage pricing theory' (see for example S. Ross, 'The arbitrage theory of capital asset pricing', J. Economic Theory, vol. 13, pp. 341-360, 1976). The theory postulates that a given vector of prices (for example, today's price for a set of stocks) can be explained by a linear combination of underlying economic components. While there is apparently substantial debate in the economic community as to the viability of the arbitrage pricing theory, this application provides a tool to test it out on real data. Who can best make use of this application: It is hoped that any user who can download stock price data into MetaStock text format will find PickStock sufficiently easy to use. Facility in handling text files and importing them into spreadsheets is also a plus. Economists and stock analysts may be able to utilize the program along with a more traditional analysis of economic fundamentals. Scientists, engineers, and students may even be able to tap into the powerful principal components analysis engine that PickStock incorporates by replacing closing prices with arbitrary data (ie. a given 'date' can be associated with one experiment having outputs for each of the 'tickers' with the output values corresponding to the ticker being in the 'close' field).

statistiXL

statistiXL is a powerful new data analysis package that runs as an add-in to Windows versions of Microsoft Excel. statistiXL has been entirely designed and written by scientists in order to meet the demanding needs of anyone requiring access to a robust, versatile statistical analysis package that is quick to learn and easy to use. With its wealth of features, Excel provides an ideal environment for data input, manipulation and calculation and by leveraging this familiar environment, statistiXL greatly extends this feature set to encompass high powered statistical analysis without the need to learn how to use an entirely new application from scratch. Data stored in existing spreadsheets can instantly be subjected to a wide range of statistical tests (many frequently not seen in other analysis packages). Tests provided by statistiXL include (but are not limited to), Analysis of Variance, Cluster Analysis, Contingency Tables, Correlation (Simple, Partial, Multiple and Canonical), Linear and Circular Descriptive Statistics, Classification and Grouping Discriminant Analysis, Factor Analysis, Goodness of Fit Tests such as Binomial, Circular, Normal and Poisson, Simple and Multiple Linear Regression, Nonparametric Tests such as Friedman, Kruskal-Wallis and Mann-Whitney, Principal Component Analysis, Univariate and Multivariate t-Tests. statistiXL also produces a wide range of plots including Box and Whisker Plots, Scatter Plots, Clustering Dendrograms, Normal Probability Plots and many others. Numerous options exist for formatting the standard results that are outputted by statistiXL and because these results are placed into Excel spreadsheets, you can use the tools that you are already familiar with to arrange and format textual and graphical output even further, changing fonts, rearranging cells, altering the scale on the axis of a graph etc etc. You can even subject the results to further analysis using either statistiXL or any of Excels numerous built in functions.

SplitCam

SplitCam virtual video capture driver allows for connecting several applications to a single video capture source. For example, if you have a web-camera connected to your computer you cannot use it in more than one application at the same time - there?s no standard Windows options that would make it possible. SplitCam does just what its name says: it splits the video stream coming from the video source and provides it to other client applications
