In this paper, a new method for computing the standard errors (SEs) of returns-based risk and performance estimators for serially dependent returns is developed. The method uses both the fact that any ...

Horvitz-Thompson estimators based on estimated inclusion probabilities are developed for line transect surveys in which some of the central assumptions of conventional line transect theory fail. The ...

The numerical example given shows that the estimators suggested in this article provide lower variances in certain cases than the Hartley estimators. These estimators are also simpler to compute and ...

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 ...

Our Monte Carlo simulation results indicate that the widely-used least squares estimations of the Vasicek model suffer significant small-sample biases even if the sample length reaches as long as 30 ...

With more than 35 years of experience as a construction electrician, industrial maintenance electrician, foreman, estimator, estimating manager, and project manager, Don has used what he learned to ...

A long time ago I had a client whose estimators didn’t account for traffic delays on a job in Boston and it ended up costing them big. They were estimating an 8 hour day on the job but on ...
