Clustered person-year standard errors in parenthesis.*** statistically significant at 1%, ** statistically significant at 5%, * statistically significant at 10%.
Association between deciles of HbA1c and all-cause admission was assessed using logistic regression models clustered by person.
With the use of clusters, persons may be considered in broad terms; in addition, subgroups may be correlated with clinical and socio-demographic variables and patterns of service use [ 34].
In this part of our analysis, the unit of observation is the person-year, so the corresponding standard errors for the marginal effects are clustered at the person-year level.
In Naogaon, we identified 12 cases (4 confirmed, 8 probable); 7 were in persons clustered in 2 households.
Infection of secondary cases was clustered among few persons; 6 source-patients, all of whom died in the community, accounted for more than half of the cases in this report.
In VREF isolates, we could identify four genogroups, which were associated with particular hosts and environments and in which most isolates from healthy persons clustered distinctly from patient isolates.
Laws which provide for welfare, care, protection and rehabilitation of young persons are clustered under the Children and Young Persons Act.
The four methods compared are logistic regression accounting neither person nor item clustering effect, hierarchical logistic regression accounting for person clustering effect, the testlet model accounting for the item clustering effect, and the multilevel testlet model accounting for both person and item clustering effects.
Hierarchical logistic regression (HLR) is a natural choice for DIF detection in terms of accounting for the person clustering effect because of its feasibility of incorporating person dependency within clusters by a higher level regression analysis.
XMRV pol sequences from previously reported prostate cancer patients (coded with VP), except two (VP29 and VP184, kindly provided by Joe DeRisi), clustered with those from persons with CFS (coded with WPI) with significant bootstrap support.
