摘要： We give estimates on the rate of convergence on the Boolean central limit theorem for the L,vy distance. In the case of measures with bounded support, we obtain a sharp estimate by giving a qualitative description of this convergence.

摘要： For any outlier detection procedure, a key concern is robustness with respect to possible misclassification errors, masking (Type I) and swamping (Type II). Although parametric model-based simulation results are informative, one also desires nonparametric masking and robustness measures that are more broadly applicable. To this effect, notions of finite sample masking and swamping breakdown points formulated abstractly for outlyingness functions in arbitrary data settings (Serfling and Wang, 2014) are introduced in the present paper into the multivariate data setting. Formulas for the measures are derived for three important affine invariant nonparametric multivariate outlyingness functions: Mahalanobis distance, Mahalanobis spatial, and projection. Using the formulas, favorable masking and swamping breakdown points, balanced equally, are seen for the Mahalanobis distance outlyingness using minimum covariance determinant (MCD) location and scatter estimators, and likewise for the projection outlyingness with median and MAD for univariate location and scale. Also, Mahalanobis spatial outlyingness with MCD standardization is competitive when swamping robustness is given higher priority than masking robustness. A small simulation study with bivariate contaminated standard normal and contaminated exponential models yields results consistent with the theoretical formulas. Some practical recommendations are discussed. (C) 2018 Elsevier Inc. All rights reserved.

摘要： Background: Linking clinical registries to administrative claims data enables researchers to capitalize on the specific strengths of each data source with respect to the depth, breadth, and completeness of information. The objectives of this study were to link a health-system-based orthopaedic surgery registry to U.S. Medicare claims data without the use of unique identifiers and to assess the representativeness of the linked records. Methods: The registry included clinical data for patients >= 65 years of age who underwent elective, inpatient total ankle arthroplasty (TAA) in a single health system during the period of 2007 through 2012. Registry participants were identified within the Medicare data by linking registry procedures to TM procedures within the claims data using a combination of procedure date, patient date of birth, and patient sex. We assessed the representativeness of the linked records by comparing them to both unlinked registry records and unlinked Medicare records for TAA procedures. Additionally, we described the availability of postsurgical data for linked records. Results: Of 360 TAA registry participants >= 65 years of age, 280 (77.8%) were matched to a Medicare record;250 (89.3%) of those 280 participants were matched on the basis of a linking rule that required an exact match for procedure date, date of birth, and sex. The 280 linked records comprised 5.5% of all Medicare TAA procedures among beneficiaries 65 years of age enrolled in the fee-for-service Medicare program (n = 5,070). Compared with linked records, unlinked records were more likely to be for patients 65 to 69 years old, but the 2 groups were similar in terms of sex, body mass index, and availability of clinical measurements. Of the linked records, 214 (76.4%) had >= 3 years of postoperative followup claims data. Conclusions: Linkage without unique patient identifiers between an orthopaedic registry and Medicare claims data is feasible, allows for assessment of representativene
