— width of bar shows percent of time each method is used in a suicide attempt — by implication, the area of each bar represents the total number of lethal attempts for each method.

For example, if both p-values are around 0.10, or if one is around 0.04 and one is around 0.25, the meta-analysis p-value is around 0.05. In statistics, Fisher's method, [1] [2] also known as Fisher's combined probability test, is a technique for data fusion or "meta-analysis" (analysis of analyses).
In probability theory and statistics, the F-distribution or F-ratio, also known as Snedecor's F distribution or the Fisher–Snedecor distribution (after Ronald Fisher and George W. Snedecor), is a continuous probability distribution that arises frequently as the null distribution of a test statistic, most notably in the analysis of variance (ANOVA) and other F-tests.
For this reason, it is preferable to use the t distribution rather than the normal approximation or the chi-squared approximation for a small sample size. Similarly, in analyses of contingency tables, the chi-squared approximation will be poor for a small sample size, and it is preferable to use Fisher's exact test.
Hammond Edward "Ham" Fisher (September 24, 1900 [some sources indicate 1901] – December 27, 1955) was an American comic strip writer and cartoonist. He is best known for his long, popular run on Joe Palooka , which was launched in 1930 and ranked as one of the top five newspaper comics strips for several years.
Scoring algorithm, also known as Fisher's scoring, [1] is a form of Newton's method used in statistics to solve maximum likelihood equations numerically, named after Ronald Fisher. Sketch of derivation
In the United States, suicide is around 4.5 times more common in men than in women. [25] U.S. men are 5 times as likely to die from suicide within the 15- to 19-year-old demographic, and 6 times as likely as women to die from suicide within the 20- to 24-year-old demographic. [22]
The Fisher information matrix is used to calculate the covariance matrices associated with maximum-likelihood estimates. It can also be used in the formulation of test statistics, such as the Wald test. In Bayesian statistics, the Fisher information plays a role in the derivation of non-informative prior distributions according to Jeffreys ...
