Comparison of Semiparametric Models in the Presence of Noise and Outliers

Journal of Applied Mathematics
Various studies have examined generalized additive models (GAMs), comparing thin plate splines (tp), P-splines (ps), cubic regression splines (cr), and Gaussian processes (gp) for discrete choice data, function approximation, and in the presence of ...

Time Series Analysis of the Southern Oscillation Index using Bayesian Additive Regression Trees [PDF]

arXiv, 2018
Bayesian additive regression trees (BART) is a regression technique developed by Chipman et al. (2008). Its usefulness in standard regression settings has been clearly demonstrated, but it has not been applied to time series analysis as yet. We discuss the difficulties in applying this technique to time series analysis and demonstrate its superior ...

Incorporating familial risk, lifestyle factors, and pharmacogenomic insights into personalized noncommunicable disease (NCD) reports for healthcare funder beneficiaries participating in the Open Genome Project

Annals of Human Genetics, EarlyView.
Abstract Introduction An ethics‐guided decision‐making framework was developed for applying pathology‐supported genetic testing, a multifaceted pharmacodiagnostic approach that translates population risk stratification into clinical utility. We introduce this service, supported by the Open Genome Project, which aligns with the beneficence principle in ...

Pay-As-You-Drive Insurance Pricing Model [PDF]

American Journal of Statistics and Actuarial Science, Vol.2, Issue 1, pp 1 - 9, 2020, 2019
Every time drivers take to the road, and with each mile that they drive, exposes themselves and others to the risk of an accident. Insurance premiums are only weakly linked to mileage, however, and have lump-sum characteristics largely. The result is too much driving, and too many accidents.

Mapping agents: A spatial economic analysis of agent location in the Federal Crop Insurance Program

American Journal of Agricultural Economics, EarlyView.
Abstract Crop insurance is delivered to farmers and ranchers through a partnership among the Federal Crop Insurance Corporation (FCIC), part of the United States Department of Agriculture, and the crop insurance industry. The FCIC offers financial incentives, through reinsurance and subsidies, to private insurance companies for insurance contracts sold

Experiential Learning, Narrative‐Based Learning, and Insurance Adoption: Experimental Evidence from Kenya

American Journal of Agricultural Economics, EarlyView.
Abstract We compare the impact of two extension modalities on knowledge accumulation and willingness to pay for a weather index insurance product among smallholder farmers in Kenya. One approach to extension is based on experiential learning and involves participation in an incentivized framed experiment (or game).

How data or error covariance can change and still retain BLUEs as well as their covariance or the sum of squares of errors

Australian &New Zealand Journal of Statistics, EarlyView.
Summary Misspecification of the error covariance in linear models usually leads to incorrect inference and conclusions. We consider two linear models, A$$ \mathcal{A} $$ and B$$ \mathcal{B} $$, with the same design matrix but different error covariance matrices. The conditions under which every representation of the best linear unbiased estimator (BLUE)
