We present the R package and web app "statcheck" to automatically detect statistical reporting inconsistencies in primary studies and meta-analyses. Previous research has shown a high prevalence of reported p-values that are inconsistent--meaning a re-calculated p-value, based on the reported test statistic and degrees of freedom, does…

Network meta-analysis (NMA) is gaining popularity for comparing multiple treatments in a single analysis. Generalized linear mixed models provide a unifying framework for NMA, allow us to analyze datasets with dichotomous, continuous or count endpoints, and take into account multiarm trials, potential heterogeneity between trials and network…

Bad smells affect maintainability and performance of model-to-model transformations. There are studies that define a set of transformation bad smells, and some of them propose techniques to recognize and--according to their complexity--fix them in a (semi)automated way. In academia it is necessary to make students aware of this subject and provide…

Item response theory parameters have to be estimated, and because of the estimation process, they do have uncertainty in them. In most large-scale testing programs, the parameters are stored in item banks, and automated test assembly algorithms are applied to assemble operational test forms. These algorithms treat item parameters as fixed values,…

Automatic item generation represents a relatively new but rapidly evolving research area where cognitive and psychometric theories are used to produce tests that include items generated using computer technology. Automatic item generation requires two steps. First, test development specialists create item models, which are comparable to templates…

Describes VisiCalc, a programmed package for use with the Apple II microcomputer and discusses the use of this program for two library tasks--statistical analysis and budgeting. System features are described in the context of these applications and six tables illustrating system output are appended. Additional resources are listed. (RAA)

Primary focus in this 1977 annual report of the Houston Public Library system is the library's nine-month program, "City...Our Urban Past, Present and Future," which was funded by a grant from the National Endowment for the Humanities. Aspects of the first four months of the program that are described include its lecture series,…

Discusses the benefits of the library collection assessment process, and describes how a small community college library is using a turnkey automated system and a microcomputer-based database program to generate special reports and statistical profiles to support an ongoing collection assessment project. (Eight references) (CLB)

Describes and illustrates Statistical Package for the Social Sciences (SPSS) procedures appropriate for book collection data analysis. Several different procedures for univariate, bivariate, and multivariate analysis are discussed, and applications of procedures for book collection studies are presented. Included are 24 tables illustrating output…

Using OCLC-MARC tape records, master records were created for collection management reports at University of Wisconsin-Whitewater to help evaluate collection growth by type of material, location, and subject, based upon LC call number. The Statistical Analysis System (SAS) was run against records to generate information for special purposes. (9…

Introduction to the second part of a two-part series on collection development invites the reader to evaluate current collection development practice while considering changes, in light of recent innovations in library automation, resource availability, and format. Three major themes discussed in as many articles are briefly reviewed. (SD)

Selecting elite students out of a huge collective is a difficult task. The main problem is to provide automated processes to reduce human work. ECMS (Educational Contest Management System) is an online tool approach to help--fully or partly automated--with the task of selecting such elite students out of a mass of candidates. International tests…
