Economic growth is typically attributed as the fundamental cause of environmental problems due to higher production which generates more pollution. The EKC hypothesis used test link between economic and In this regard, study aims ascertain validity in Somalia using time series data spanning 1989 2020. autoregressive distributed lag (ARDL) technique applied verify presence integrations sampled v...

 In this paper, a new Dynamic Geometric Genetic Programming (DGGP) technique is applied to empirical analysis of financial ratios and bankruptcy prediction. Financial ratios are indeed desirable for prediction of corporate bankruptcy and identification of firms’ impending failure for investors, creditors, borrowing firms, and governments. By the time, several methods have been attempted in...

Functional testing of SFF parts represents an exciting area of research in solid freeform fabrication. One approach to functional testing is to use similitude techniques to correlate the behavior of an SFF model and a product. Previous research at UT Austin has resulted in development of an empirical similitude technique to correlate the behavior of parts of dissimilar materials and geometry. A...

We study an increment bound for the empirical process, indexed by linear combinations of highly correlated base functions. We use direct arguments, instead of the chaining technique. We moreover obtain bounds for an M-estimation problem inserting a convexity argument instead of the peeling device. Combining the two results leads to non-asymptotic bounds with explicit constants. Let us motivate ...

Previous empirical research has shown that Mexico's Oportunidades program has succeeded in increasing schooling and improving health of disadvantaged children. This paper studies the program's potential longer-term consequences for the poverty and inequality of these children. It adapts methods developed in DiNardo, Fortin and Lemieux (1996) and incorporates existing experimental estimates of t...

This article reviews existing empirical research on the effect of eight legal levers on outcomes related to child maltreatment. Laws created with the intent to address child maltreatment are oft...

In this paper we develop dual free SDCA with adaptive probabilities for regularized empirical risk minimization. This extends recent work of Shai Shalev-Shwartz [SDCA without Duality, arXiv:1502.06177] to allow non-uniform selection of ”dual” coordinate in SDCA. Moreover, the probability can change over time, making it more efficient than uniform selection. Our work focuses on generating adapti...

This paper aims to provide direct and indirect evidence on setting up rules for applications of the empirical Bayes shrinkage (EBS), and offers cautionary remarks concerning its applicability. In epidemiology, there is still a lack of relevant criteria in the application of EBS. The bias of the shrinkage estimator is investigated in terms of the sums of errors, squared errors and absolute error...
