Depression is a major cause of morbidity and mortality worldwide, as the epidemiology has shown. [1] Lifetime prevalence estimates vary widely, from 3% in Japan to 17% in India. Epidemiological data shows higher rates of depression in the Middle East, North Africa, South Asia and the United States than in other regions and countries. [2]
The source for the data below is the OECD Health Statistics 2018, released by the OECD in June 2018 and updated on 8 November 2018. [1]The unit of measurement used by the OECD is defined daily dose (DDD), defined as "the assumed average maintenance dose per day for a drug used on its main indication in adults". [2]
This is a complete list of clinically approved prescription antidepressants throughout the world, as well as clinically approved prescription drugs used to augment antidepressants or mood stabilizers, by pharmacological and/or structural classification.
For normally distributed random variables inverse-variance weighted averages can also be derived as the maximum likelihood estimate for the true value. Furthermore, from a Bayesian perspective the posterior distribution for the true value given normally distributed observations and a flat prior is a normal distribution with the inverse-variance weighted average as a mean and variance ().
In statistics, there are many applications of "weighting": Weighted mean; Weighted harmonic mean; Weighted geometric mean; Weighted least squares
In contrast, a disease that has a short duration may have a low prevalence and a high incidence. When the incidence is approximately constant for the duration of the disease, prevalence is approximately the product of disease incidence and average disease duration, so prevalence = incidence × duration. The importance of this equation is in the ...
In statistics, the Horvitz–Thompson estimator, named after Daniel G. Horvitz and Donovan J. Thompson, [1] is a method for estimating the total [2] and mean of a pseudo-population in a stratified sample by applying inverse probability weighting to account for the difference in the sampling distribution between the collected data and the a target population.
The World Health Organization has published worldwide incidence and prevalence estimates of individual disorders. Obsessive-compulsive disorder is two to three times as common in Latin America, Africa, and Europe as in Asia and Oceania. [7] Schizophrenia appears to be most common in Japan, Oceania, and Southeastern Europe and least common in ...
