A Reference Model For Providing Statistical Consulting Services In An Academic Library Setting, Kristi Anne Thompson, Daniel M. Edelstein

Leddy Library Publications

Princeton University Library, through its Data and Statistical Services (DSS) unit, goes further than many libraries in providing consulting on statistical methods as well as software support for data library users. Princeton requires all third and fourth year undergraduates to do independent original research papers and theses in their disciplines of concentration. These requirements create a clientele of students who need to conduct relatively sophisticated statistical analysis, but who may or may not possess the necessary skills required to do so. This paper describes the model we employ at Princeton DSS to help these patrons, drawing on our experience as …

A Comparison Of Methods For Longitudinal Analysis With Missing Data, James Algina, H. J. Keselman

Journal of Modern Applied Statistical Methods

In a longitudinal two-group randomized trials design, also referred to as randomized parallel-groups design or split-plot repeated measures design, the important hypothesis of interest is whether there are differential rates of change over time, that is, whether there is a group by time interaction. Several analytic methods have been presented in the literature for testing this important hypothesis when data are incomplete. We studied these methods for the case in which the missing data pattern is non-monotone. In agreement with earlier work on monotone missing data patterns, our results on bias, sampling variability, Type I error and power support the …

Issues In Assessing The Validity Of Nutrient Data Obtained From A Food-Frequency Questionnaire: Folate And Vitamin B12 Examples, Victoria Flood, Wayne T. Smith, Karen L. Webb, Paul Mitchell

Faculty of Social Sciences - Papers (Archive)

Objective: To compare methods used to assess the validity of nutrient intake data obtained from a food-frequency questionnaire (FFQ), using folate and vitamin B₁₂ as nutrient examples.

Design: Cross-sectional sample from a population cohort.

Setting: Two postcode areas west of Sydney, Australia.

Subjects: In total, 2895 people aged 49 years and older provided dietary data using a semi-quantitative FFQ (79% of 3654 subjects examined). The validity of the FFQ was assessed against three 4-day weighed food records (WFRs) completed by 78 people (mean age 70 years).

Results: Folate and vitamin B₁₂ validity data were assessed using different methods. …

Global CWD Repository

The MAIC built upon research conducted in earlier phases of the project (2001-2002) to investigate the following unresolved questions regarding the development of an effective landmine casualty data system.

1. 1. What kind of data about landmine victims is being collected and is it adequate to the needs of victim assistance service providers?
2. 2. If it is not adequate, what additional data should be collected and how should it be managed?
3. 3. What can be done to improve the dissemination of landmine casualty data?

These questions were addressed by investigating developments in landmine casualty data collection and management since 2002 and …
