查询词典 risk

Five ways on comparing covariance matrix are applied to the Shanghai 50 Indexes Stock Exchange, which are sample covariance matrix, scalar matrix, two-parameter covariance matrix, single index matrix, constant correlation matrix. We adopt principal components method and Markowitz portfolio method to measure stock market risk using VaR, getting the effect of measuring market risk. The result shows that sample covariance matrix and two-parameter covariance matrix could measure market risk more effectively.

Approximately 5% of subjects who had a perforation died within 14 days of the procedure. Risk of death was significantly increased by perforation after colonoscopy (OR, 9.0; 95% CI, 3.0 - 27.3) or after sigmoidoscopy (OR, 8.8; 95% CI, 1.6 - 48.5). The difference in risk between the two procedures has been narrowing because the risk of perforation from colonoscopy has decreased over the years, presumably from improvements in technology and in training.
