Cross correlation matrix and random matrix theory - repost

BACKGROUND of this project We are trying to apply a method of scientific research to our business (manufacturing). We want to make an efficient production plan. For volatile demand, we have to have a surplus stocks and workers to win the market. So we have to know the demand trend and volatility for each product. The method shown in the paper below is data-leading method. It extracts the market trend only from the data. (c.f. Auto-regression model is theory-leading method. It puts data into polynomials. It is just a coefficient fitting method. So polynomials must be supported by the other theory) When you achieve this project, your analysis skills and scientific knowledge will be assured. Also you will be able to add the production management skill to your portfolio. We set well defined mile stones described in the requirements field below. For each mile stone, we will make a go/no-go decision for hiring. We wish to make a long-term ongoing relationship with you (longer than a year). We wii take those abilities shown below into consideration for go/no-go decisions. lead-time for each mile stones (not working hours) quality of source codes data analysis skills the knowledge of physics and mathematics (in preferential order) You MUST read the attached file which describes the derail of this project. >Added on Jan 2, 2013 16:00 JST I found the pre-print of the reference paper.
