conditional copula-garch methods for value at risk of portfolio: the case of tehran stock exchange market
ارزش در معرض ریسک یکی از مهمترین معیارهای اندازه گیری ریسک در بنگاه های اقتصادی می باشد. برآورد دقیق ارزش در معرض ریسک موضوع بسیارمهمی می باشد و انحراف از آن می تواند موجب ورشکستگی و یا عدم تخصیص بهینه منابع یک بنگاه گردد. هدف اصلی این مطالعه بررسی کارایی روش copula-garch شرطی در برآورد ارزش در معرض ریسک پرتفویی متشکل از دو سهام می باشد و ارزش در معرض ریسک بدست آمده با روشهای سنتی برآورد ارزش د...
Vasoepididymostomy for vasectomy reversal: a critical assessment in the era of intracytoplasmic sperm injection.
PURPOSE We compared vasoepididymostomy to microsurgical epididymal sperm aspiration and intracytoplasmic sperm injection for treatment of epididymal obstruction secondary to vasectomy. MATERIALS AND METHODS Results in patients who underwent vasoepididymostomy for vasectomy reversal at our institution were compared to those reported previously for microsurgical epididymal sperm aspiration and ...
متن کاملPatient characteristics associated with vasectomy reversal.
PURPOSE More than 30 million couples throughout the world are using vasectomy as a method of birth control. It is estimated that up to 6% of men who undergo voluntary sterilization will eventually request reversal, despite the high cost and relatively low success rate of the procedure. We identified characteristics that predict which vasectomy patients may request reversal. We also examined the...
متن کاملModel to predict if a vasoepididymostomy will be required for vasectomy reversal.
PURPOSE We devised a model to predict, preoperatively, the need for a vasoepididymostomy (VE) when performing a vasectomy reversal. Urologists could use it to identify those patients who need a referral to an experienced VE surgeon. MATERIALS AND METHODS We performed a retrospective review of 483 patients who underwent vasectomy reversal by a single surgeon (AJT) including 393 vasovasostomies...
متن کاملThe need for epididymovasostomy at vasectomy reversal plateaus in older vasectomies: a study of 1229 cases
Vasectomy reversal involves either vasovasostomy (VV) or epididymovasostomy (EV), and rates of epididymal obstruction and EV increase with time after vasectomy. However, as older vasectomies may not require EV for successful reversal, we hypothesized that sperm production falls after vasectomy and can protect the system from epididymal blowout. Our objective was to define how the need for EV at...
