INFERENCE FOR NORMAL MIXTURES IN MEAN AND VARIANCE
A finite mixture of normal distributions, in both mean and variance parameters, is a typical finite mixture in the location and scale families. Because the likelihood function is unbounded for anyExpand

Eliminating Bias in Classify-Analyze Approaches for Latent Class Analysis
Despite recent methodological advances in latent class analysis (LCA) and a rapid increase in its application in behavioral research, complex research questions that include latent class variablesExpand

Effect Size, Statistical Power, and Sample Size Requirements for the Bootstrap Likelihood Ratio Test in Latent Class Analysis
Selecting the number of different classes that will be assumed to exist in the population is an important step in latent class analysis (LCA). The bootstrap likelihood ratio test (BLRT) provides aExpand

New variable selection methods for zero-inflated count data with applications to the substance abuse field.
Zero-inflated count data are very common in health surveys. This study develops new variable selection methods for the zero-inflated Poisson regression model. Our simulations demonstrate the negativeExpand

Measurement of brain perfusion in newborns: Pulsed arterial spin labeling (PASL) versus pseudo-continuous arterial spin labeling (pCASL)
Background Arterial spin labeling (ASL) perfusion-weighted imaging (PWI) by magnetic resonance imaging (MRI) has been shown to be useful for identifying asphyxiated newborns at risk of developingExpand

CONSISTENCY OF PENALIZED MLE FOR NORMAL MIXTURES IN MEAN AND VARIANCE Running Title: Consistency of Estimates in Normal Mixture
The finite mixture of normal distributions in both mean and variance parameters have wide applications. It is well known that the likelihood function of this model is unbounded for any given sampleExpand

Preemptive Use of Gabapentin in Abdominal Hysterectomy: A Systematic Review and Meta-analysis
OBJECTIVE: To examine the evidence of preemptive use of gabapentin in abdominal hysterectomy. DATA SOURCES: We conducted an electronic based search using the following databases: PubMed, EMBASE, OvidExpand

Does near-infrared spectroscopy identify asphyxiated newborns at risk of developing brain injury during hypothermia treatment?
OBJECTIVE The aim of this article is to assess whether near-infrared spectroscopy (NIRS) identifies, during hypothermia treatment, the asphyxiated newborns who later develop brain injury. STUDYExpand

Intraventricular hemorrhage in asphyxiated newborns treated with hypothermia: a look into incidence, timing and risk factors
BackgroundIntraventricular hemorrhage (IVH) is uncommon in term newborns. Asphyxia and hypothermia have been mentioned separately as possible risk factors of IVH, since they might cause fluctuationsExpand
