Анализ краткосрочных тенденций в российской экономике: как рассеять "туман настоящего"?
The article reveals the content of «mirror statistics» method (in the framework of international comparative analysis) which is implemented to improve statistical information on external economic activity. Main reasons of discrepancies in data are considered and recommendations how to decrease these discrepancies are proposed.
The general region socio-economical developement estimation approach is based on the agregation of diffeerent indices into one number. This approach leads to the loss of information, because highly economically developed regions are mixed with the poorly developed regions which live only due to subsidies. The new complex-valued index is proposed in the article. The usage of the index allows to evaluate the regions' developement from two separated sides: the social developement and economical developement. The simple way of such a complex-valued indices is proposed in the article.
The paper analyzes storage peculiarities of satellite Earth remote sensing data time series. We propose methods for their compression based on the discovered peculiarities exploiting different schemes of Huffman coding. One of the proposed methods reaches 6% increase in the compression ratio (93%) in contrast to the deflate method used in Java SE6 (87%), for a time series of aerosol optical thickness derived from MODIS radiometer of TERRA satellite. Further improvement can be achieved by using the entropy coding of floating point numbers.
