Modelling Placebo Response via Infinite Mixtures.

JP journal of biostatistics

Tarpey T, Petkova E.
PMID: 21804745
JP J Biostat. 2010 Jun 01;4(2):161-179.

Non-specific treatment response, also known as placebo response, is ubiquitous in the treatment of mental illness, particularly in treating depression. The study of placebo effect is complicated because the factors that constitute non-specific treatment effects are latent and not...

LATENT CLASS MODELING USING MATRIX COVARIATES WITH APPLICATION TO IDENTIFYING EARLY PLACEBO RESPONDERS BASED ON EEG SIGNALS.

The annals of applied statistics

Jiang B, Petkova E, Tarpey T, Ogden RT.
PMID: 29152032
Ann Appl Stat. 2017 Sep;11(3):1513-1536. doi: 10.1214/17-AOAS1044. Epub 2017 Oct 05.

Latent class models are widely used to identify unobserved subgroups (i.e., latent classes) based upon one or more manifest variables. The probability of belonging to each subgroup is typically modeled as a function of a set of measured covariates....

BACKGROUND: Haemophilias are the most common hereditary severe disorders of blood clotting. In families afflicted with heamophilia, genetic analysis provides opportunities to prevent recurrence of the disease. This study establishes a diagnostical strategy for carriership determination and prenatal diagnostics...

Model Misspecification: Finite Mixture or Homogeneous?.

Statistical modelling

Tarpey T, Yun D, Petkova E.
PMID: 18974843
Stat Modelling. 2008;8(2):199-218. doi: 10.1177/1471082X0800800204.

A common problem in statistical modelling is to distinguish between finite mixture distribution and a homogeneous non-mixture distribution. Finite mixture models are widely used in practice and often mixtures of normal densities are indistinguishable from homogenous non-normal densities. This...

The outcome of umbilical cord blood transplantation (UCBT) is compromised by low hematopoietic stem cell (HSC) doses leading to prolonged time to engraftment, delayed immunological reconstitution and late memory T-cell skewing. Exposure of UCB to dimethyl-prostaglandin E2 (dmPGE2) increases...
