MathematicsThe Cox proportional hazards (PH) model is widely used because it models the covariates to the hazard through a log-linear effect. However, exploring flexible effects becomes desirable within the Cox PH framework when only a monotonic relationship ...

Partial mixture model for tight clustering of gene expression time-course
BMC Bioinformatics, 2008 Background Tight clustering arose recently from a desire to obtain tighter and potentially more informative clusters in gene expression studies. Scattered genes with relatively loose correlations should be excluded from the clusters.

Partial trisomy 9: prenatal diagnosis and recurrence within same family
Clinical Case Reports, 2017 Key Clinical Message Trisomy 9 can be suspected and confirmed in the prenatal period since the 11–13.6 weeks of screening. In cases of partial trisomy 9, the diagnosis is important especially to counseling the couple due to the increased likelihood of ...

Bayesian Inference in Auditing with Partial Prior Information Using Maximum Entropy Priors
Entropy, 2018 Problems in statistical auditing are usually one⁻sided. In fact, the main interest for auditors is to determine the quantiles of the total amount of error, and then to compare these quantiles with a given materiality fixed by the auditor, so that ...

The Annals of Statistics, 1986 This paper develops the asymptotic theory: consistency and asymptotic normality for estimators of a parameter \(\theta\) based upon partial likelihood or conditional likelihood in a rather general setting. It includes most of the results obtained in this area, among them we can quote \textit{J. D. Kalbfleisch} and \textit{D. A. Sprott} [J. R. Stat. Soc.

The asymptotic local structure of the Cox modified likelihood-ratio statistic for testing non-nested hypotheses [PDF]
, 1992 It is shown that the Cox modified likelihood-ratio statistic for testing partially non-nested hypotheses H0 and H1 is asymptotically equivalent to a bilinear form in nondegenerate asymptotically normal random vectors for sequences of data-generating ...

MachinesThe Proportional Hazards Model (PHM) under a Condition-Based Maintenance (CBM) policy is used by asset-intensive industries to predict failure rate, reliability function, and maintenance decisions based on vital covariates data.

Sample Empirical Likelihood under Complex Survey Design and Bayesian Jackknife Empirical Likelihood-based Inference for Missing Data and Partial AUC [PDF]
The empirical likelihood (EL), introduced by Owen (1988, 1990), is a powerful tool for constructing confidence intervals in nonparametric settings. Significant developments based on empirical likelihood have been made in recent years.

Trends in the Use of Nephron-Sparing Surgery over 7 Years: An Analysis Using the R.E.N.A.L. Nephrometry Scoring System. [PDF]
PLoS ONE, 2015 To analyze trends in the use of partial nephrectomy, we evaluated which individual factors of renal nephrometry score (RNS) influenced the operative approach bi-annually from 2008 to 2014.We performed a retrospective review of renal cell carcinoma ...

Approximating Partial Likelihood Estimators via Optimal Subsampling
Journal of Computational and Graphical Statistics, 2023 With the growing availability of large-scale biomedical data, it is often time-consuming or infeasible to directly perform traditional statistical analysis with relatively limited computing resources at hand. We propose a fast subsampling method to effectively approximate the full data maximum partial likelihood estimator in Cox's model, which largely ...
