Disclosure Risk from Factor Scores in a Remote Access Environment
Remote access is a promising tool for broadening the access to microdata without violating confidentiality requirements. In a remote access setting the user submits queries to a system provided by the statistical agency and only the results of the queries are reported back to the user. Since no direct access to the data is granted, generally no alteration of the underlying microdata is required...
متن کاملSummarization of Corporate Risk Factor Disclosure through Topic Modeling
In this paper, we propose a novel problem of summarizing textual corporate risk factor disclosure, which aims to simultaneously infer the risk types across corpus and assign each risk factor to its most probable risk type. To solve the problem, we develop a variation of LDA topic model called Sent-LDA. The variational EM learning algorithm, which guarantees fast convergence, is derived and impl...
متن کاملPreterm Birth: A Prominent Risk Factor for Low Apgar Scores
OBJECTIVE To determine predictive risk factors for Apgar scores < 7 at 5 minutes at two hospitals providing tertiary care and secondary care, respectively. METHODS A retrospective registry cohort study of 21126 births (2006-2010) using data from digital medical records. Risk factors were analyzed by logistic regression analyses. RESULTS AS(5 min) < 7 was multivariately associated with the f...
متن کاملPRAM and Disclosure Risk
Statistical Disclosure Control is part of the usual process, necessary for the dissemination of microdata. Usually, direct identifiers are removed and variables that can be used to re-identify certain records are recoded or suppressed. For certain surveys these methods are inadequate to produce safe microdatasets with enough detail, to satify both the supplier and the user of these sets. To tha...
متن کاملDisclosure and Rollover Risk
This paper studies whether and to what extent transparent disclosure prevents inefficient liquidation arising from rollover risk. We model an illiquid but solvent borrower who can design a public signal about what creditors can recover from forcing liquidation, and what their claims would be worth if the firm survives. We find that the signal structure that minimizes rollover risk never identif...
