Score tests based on a finite mixture model of Markov processes under intermittent observation
No full textThis is the peer reviewed version of the following article: Shu Jiang and Richard J. Cook, Score tests based on a finite mixture model of Markov processes under intermittent observation, Statistics in Medicine (2019), 38(16): 3013–3025 which has been published in final form at https://doi.org/10.1002/sim.8155. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Use of Self-Archived Versions.A mixture model is described, which accommodates different Markov processes governing disease progression in a finite set of latent classes. We give special attention to the setting in which individuals are examined intermittently and transition times are consequently interval censored. A score test is developed to identify genetic markers associated with class membership. Simulation studies are conducted to validate the algorithm, assess the finite sample properties of the estimators, and assess the frequency properties of the score tests. A permutation test is recommended for settings when there is concern that the asymptotic approximation to the score test is poor. An application involving progression in joint damage in psoriatic arthritis (PsA) provides illustration and identifies human leukocyte antigen markers associated with unilateral and bilateral sacroiliac damage in individuals with PsA.This research was supported through grants from the Natural Sciences and Engineering Research Council of Canada (RGPIN 155849 and RGPIN 04027) and the Canadian Institutes for Health Research (FRN 13887) awarded to Richard Cook.

Where Participatory Approaches Meet Pragmatism in Funded (Health) Research: The Challenge of Finding Meaningful Spaces
No full textThe term participatory research is now widely used as a way of categorising research that has moved beyond researching "on" to researching "with" participants. This paper draws attention to some confusions that lie behind such categorisation and the potential impact of those confusions on qualitative participatory research in practice. It illuminates some of the negative effects of "fitting in" to spaces devised by other types of research and highlights the importance of forging spaces for presenting participatory research designs that suit a discursive approach and that allow the quality and impact of such research to be recognised. The main contention is that the adoption of a variety of approaches and purposes is part of the strength of participatory research but that to date the paradigm has not been sufficiently articulated. Clarifying the unifying features of the participatory paradigm and shaping appropriate ways for critique could support the embedding of participatory research into research environments, funding schemes and administration in a way that better reflects the nature and purpose of authentic involvement
Adaptive sampling in two-phase designs: a biomarker study for progression in arthritis
No full textResponse‐dependent two‐phase designs are used increasingly often in epidemiological studies to ensure sampling strategies offer good statistical efficiency while working within resource constraints. Optimal response‐dependent two‐phase designs are difficult to implement, however, as they require specification of unknown parameters. We propose adaptive two‐phase designs that exploit information from an internal pilot study to approximate the optimal sampling scheme for an analysis based on mean score estimating equations. The frequency properties of estimators arising from this design are assessed through simulation, and they are shown to be similar to those from optimal designs. The design procedure is then illustrated through application to a motivating biomarker study in an ongoing rheumatology research program.

Dependence modeling for multi‐type recurrent events via copulas
No full textThis is the peer reviewed version of the following article: Jooyoung Lee and Richard J. Cook, Dependence modeling for multi-type recurrent events via copulas, Statistics in Medicine (2019), 38(21): 4066–4082 which has been published in final form at https://doi.org/10.1002/sim.8283.This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Use of Self-Archived Versions.When several types of recurrent events may arise, interest often lies in marginal modeling and studying the nature of the dependence structure. In this paper, we propose a multivariate mixed-Poisson model with the dependence between events accommodated by type-specific random effects which are associated through use of a Gaussian copula. Such models retain marginal features with a simple interpretation, reflect the heterogeneity in risk for each type of event, and provide insight into the dependence between the different types of events. Semiparametric inference is proposed based on composite likelihood to avoid high dimensional integration. An application to a study of nutritional supplements in malnourished children is given in which the goal is to evaluate the reduction in the rate of several different kinds of infection.This research was supported by grants from the Natural Sciences and Engineering Research Council of Canada (RGPIN 155849) and the Canadian Institutes for Health Research (FRN 13887).
