Measure the Degree of Transparency in Accounting Disclosure of Iraqi Industrial Companies Listed in the Iraqi Market for Securities and Its Future Forecasting

THE IRAQI MAGAZINE FOR ADMINISTRATIVE SCIENCES, Volume 12, Issue 47, Pages 1-40

The research aims to measure the degree of transparency in the disclosure of the Iraqi industrial companies listed market Iraq Securities and predict the future of these companies by relying on its future expectations and measure the impact of the degree of transparency in the disclosure of the industrial companies on the closure of the company shares and future prospects rates were determined nature of the relationship between research variables, whether positive or counterproductive, and the search results that the degree of transparency in the disclosure of these companies was weak and by 47% for non-disclosure of the research sample for most items S & P scale and through the Tobin measure's q were measured profitability and performance expected result it was 3.543, a high percentage for the period (2011-2014) was the relationship statistically between the degree of transparency in the disclosure and the outlook for corporate results were varying between positive and negative also been defining the relationship between the degree of transparency in the disclosure and closing prices on the one hand and on the other hand, the relationship between the closing prices and the outlook through the use of the correlation coefficient. .

Comparing Different Algorithms for Estimating parameters and Reliability Function of weibull distribution

THE IRAQI MAGAZINE FOR ADMINISTRATIVE SCIENCES, Volume 12, Issue 47, Pages 350-363

Today computational techniques play an important role in various fields. In this research was to use the language of Matlab programming to simulate and compare three different algorithms are used to estimate the parameter (α,β) and reliability function of two parameters weibulldistribution.the estimation algorithms are moment estimators , maximumlikeihoodestimatorsand L_moment estimators algorithms which implemented on different sample n.and each algorithms is repeated (R=1000),and the results of estimation for parameters and reliability function are compared using statistical measure mean square error and all result are explained in tables.
