BACKGROUND Older meta-analyses of the effects of psychological treatments for depression in older adults have found that these treatments have large effects. However, these earlier meta-analyses also included non-randomized studies, and did not include newer high-quality randomized controlled trials. METHODS We conducted a meta-analysis of randomized studies on psychological treatments for de...

Statistical criteria for forecast quality in practice have limited relevance. They can be valid only in the context of a set of untested assumptions which are usually unknown and certainly difficult to judge for the client. Three non-statistical criteria are stressed: logical coherence, economic coherence, and stability. These criteria are best served by the use of structural models. As loss fu...

OBJECTIVE This study aimed to simplify the diagnostic criteria of pre-hypertension (pre-HTN) and hypertension (HTN) in the pediatric age group, and to determine the accuracy of these simple indexes in a nationally-representative sample of Iranian children and adolescents. METHOD The diagnostic accuracy of the indexes of systolic blood pressure-to-height ratio (SBPHR) and diastolic BPHR (DBPHR...

OBJECTIVE To carry out a metaanalysis of antidepressant studies to calculate the effect sizes for antidepressant effect in depressive disorder. METHOD A metaanalysis of all antidepressant studies that included an active comparison drug as well as placebo was used to calculate the effect size. Articles were selected from a MEDLINE search for the period January 1966 to June 1995. Forty-nine stu...

Many statistical models and learning machines which have hierarchical structures, hidden variables, and grammatical rules are not regular but singular statistical models. In singular models, the log likelihood function can not be approximated by any quadratic form of a parameter, resulting that conventional information criteria such as AIC, BIC, TIC or DIC can not be used for model evaluation. ...

The criteria of quality of the European Statistical System and the process analysis practiced by the German Statistical Offices are analyzed to see if they can be taken to enhance Internet based databases of agriculture and food economy. As an example these approaches were applied to the database of the ZDS in Germany. Results show that the quality criteria and the process analysis both can yie...

A structured interview was used to examine the 1-year incidence and prevalence of depression among 116 first-year university students. While 24 of the subjects (20.7%) met the Diagnostic and Statistical Manual of Mental Disorders 4th ed. (DSM-IV) criteria for Major Depressive Episode (MDE), 62 (53.4%) met the Diagnostic and Statistical Manual of Mental Disorders 3rd ed. Revised (DSM-III-R) crit...

Perception of faces and voices plays a prominent role in human social interaction, making multisensory integration of cross-modal speech a topic of great interest in cognitive neuroscience. How to define potential sites of multisensory integration using functional magnetic resonance imaging (fMRI) is currently under debate, with three statistical criteria frequently used (e.g. super-additive, m...
