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 ...

Cost Estimators made a median salary of $74,740 in 2023. The best-paid 25% made $96,740 that year, while the lowest-paid 25% made $57,130.

This paper investigates a property of estimators called stability. The stability exponent of an estimator is defined to be a measure of the effect of any single observation in the sample on the ...

Improved estimators of security price volatilities are formulated. These estimators employ data of the type commonly found in the financial pages of a newspaper: the high, low, opening, and closing ...

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 ...

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 ...

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, ...

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 ...
