Major crisis still ahead, past one was minor/Büyük krizler hala önümüzde, geçen kriz küçüktü.

Eng.Senior Research Scholar at Yale University Immanuel Wallerstein believes that the real economic crisis is still up ahead. According to Wallerstein, last years collapse was its minor version. For further readings you can have a look to his offical web site http://www.iwallerstein.com

Tr.Yale Üniversitesinden Kıdemli Araştırmacısı Immanuel Wallerstein, gerçek ekonomik krizin hala önümüzde olduğuna inanıyor.Wallerstein'a göre son yılların çöküşü gerçek ekonomik krizin yalnızca küçük bir uyarlamasıydı.

Erratum For The 5th Edition Of William Greene's Econometric Analysis

In William Greene's favorite book "Econometric Analysis, 5e" , the ACF and PACF calculations reported for Table 20.1 were incorrect. Using the same data, i posted the true calculations to Mr.Greene. And Mr.Greene posted my corrections kindly on ERRATA and DISCUSSION web page of his book.

My Article "Application Of Maksimum Entropy In Portfolio Selection" is published in Journal of the School of Business Administration, Istanbul University

In this paper, mean-variance-skewness (MVS) model is proposed first for optimal portfolio selection from financial assets, and then mean-variance-skewness-entopy (MVSE) model by adding entropy measure is proposed in order to obtain well diversified portfolio. In MVS and MVSE, Pearson skewness measure which is robust and easy to calculate than traditional skewness measures is used. Both models are used in IMKB-30 for portfolio selection and the results are compared with Markowitz mean-variance (MV) model. It is showed that more efficient portfolios can be selected by MVS model than MV model.

R Graphics

One of R's strengths is the ease with which well-designed publication-quality plots can be produced, including mathematical symbols and formulae where needed. Great care has been taken over the defaults for the minor design choices in graphics, but the user retains full control.

A Special Report On Managing Information From Economist

Feb 25th 2010 | From The Economist print edition The article has a short section on technology used for such applications, including this on R: "A free programming language called R lets companies examine and present big data sets, and free software called Hadoop now allows ordinary PCs to analyse huge quantities of data that previously required a supercomputer. It does this by parcelling out the tasks to numerous computers at once. This saves time and money. For example, the New York Times a few years ago used cloud computing and Hadoop to convert over 400,000 scanned images from its archives, from 1851 to 1922. By harnessing the power of hundreds of computers, it was able to do the job in 36 hours." It's nice to see the open-source combination of Hadoop and R getting recognition as the engine behind many such large-scale problems in predictive modeling. The Economist: A different game

Living Library

The Living Library works exactly like a normal library - readers come and borrow a 'book’ for a limited period of time. There is only one difference: the Books in the Living Library are human beings, and the Books and readers enter into a personal dialogue. The Books in the Living Library are people representing groups frequently confronted with prejudices and stereotypes, and who are often victims of discrimination or social exclusion. In this library, Books cannot only speak, but they are able to reply to the readers' questions, and the Books can even ask questions and learn themselves.
