Simple 8-Designs with Small Parameters

We describe a computer search for simple designs with prescribed automor-phism groups yielding designs with parameter sets 7-In several of these cases we are able to determine the exact number of isomorphism types of designs with that prescribed automorphism group. c

8. Analytic Study Designs

In previous topics we investigated issues in defining disease and other health-related outcomes, in quantitating disease occurrence in populations, in relating disease rates to factors of interest, and in exploring and monitoring disease rates and relationships in populations. We have referred to cohort studies, cross-sectional, and case-control studies as the sources of the measures we examine...

1 Aims: Our main objective was to analyze individual determinants that lead middle-2 aged women to seek medical care for UI. 3 Methods: Observational longitudinal study among GAZEL cohort participants: 2640 4 women aged 50-62 completed a self-administered questionnaire at baseline. Eight 5 years later (2008) 2273 (86%) responded to a follow-up questionnaire. Seeking care 6 for UI was defined as...
