Applications to computing the SE of Sharpe ratio (SR) estimators for a collection of hedge funds, whose returns have varying degrees of serial dependence, show that the new methods are a considerable ...

Renmin University researchers present a comprehensive survey of sampling- and sketch-based algorithms for distinct value estimation in big data, offering insights to accelerate database queries, ...

Robust scale estimators, on the other hand, remain bounded when a single data value is replaced by an arbitrarily large or small value. The CAPABILITY procedure computes several robust measures of ...

Bias-corrected estimators could substantially reduce the small sample biases of the least squares estimations, and further project much more accurate value-at-risk and potential future exposure ...

Nine ways estimators leave time on the table. With more than 35 years of experience as a construction electrician, industrial maintenance electrician, foreman, estimator, estimating manager, and ...

Why is a weekly meeting so vital to the success of an electrical contractor? Because depending on the size of the company, salaries for estimators are typically one of the largest overhead expenses.
