The online index calculator is suspended now. Below the content and brief descripton of the service.
This educational resourse is devoted to a problem of an index construction. The index is the most informative description of an object. So, there is a set of objects. A rating is an ordering of the set according to the objects indices.
There are lots of ways to construct indices. However, when algorithms are chosen and some results obtained, the following question arises:
How to show adequacy of the calculated indices?

The basic version of the MVR Composer is issued. It could be downloaded as zipped-file (release 61) or as the latest version from sourceforge using Subversion. The readme file is here.The input data …
Time series has similar patterns. A pattern consists of several segments. Each segment could be represented as a simple parametric regression function. Thewhole pattern is the sequence of concantenated regression functions.The following information is given: …
The problem of model generation is illustrated with a linear regression model of a single variable. See the example.
LARS is one of the most effective algorithms to select linear regression models. It is not so greedy as step-wise regression and takes not so much steps as Lasso. See the example.
This is a calculator to make Ratings and Integral Indicators. To run it please do the following.
1. Download Example.xls, use “Simple” sheet.
2. Put your Objects in the 1st column starting at A2.
3. Put your Features in the 1st …
