Boosted optimal weighted least-squares [PDF]
Mathematics of Computation, 2022 This paper is concerned with the approximation of a function u u in a given subspace V m V_m of dimension m m from evaluations of the function at n n suitably chosen points. The aim is to construct an approximation of u u in V

Exploring the Relationship between Financial Ratios and Market Stock Returns [PDF]
Eurasian Journal of Business and Economics, 2018 This paper explores the relationship between financial ratios and market stock returns of 26 Qatari listed firms from 2009 to 2015. The results of Weighted Least Square (WLS) show that earnings per share, earnings yield ratio, and dividend yield ratio

A Monte Carlo Simulation Study to Assess Estimation Methods in CFA on Ordinal Data
Cauchy: Jurnal Matematika Murni dan Aplikasi, 2022 Likert-type scale data are ordinal data and are commonly used to measure latent constructs in the educational, social, and behavioral sciences. The ordinal observed variables are often treated as continuous variables in factor analysis, which may cause ...

Weighted Least Squares and Adaptive Least Squares: Further Empirical Evidence [PDF]
, 2017 This paper compares ordinary least squares (OLS), weighted least squares (WLS), and adaptive least squares (ALS) by means of a Monte Carlo study and an application to two empirical data sets. Overall, ALS emerges as the winner: It achieves most or even all of the efficiency gains of WLS over OLS when WLS outperforms OLS, but it only has very limited ...
