Among fifth and sixth grade children convergence insufficiency is 13%. In studies that used standardized definitions of convergence insufficiency, investigators have reported a prevalence of 4.2–6% in school and clinic settings.

If Sn is a sum of n real independent random variables: S n = X 1 + ⋯ + X n {\displaystyle S_ {n}=X_ {1}+\cdots +X_ {n}\,} then Sn converges almost surely if and only if Sn converges in probability. The dominated convergence theorem gives sufficient conditions for almost sure convergence to imply L1 -convergence:
In mathematics, convergence tests are methods of testing for the convergence, conditional convergence, absolute convergence, interval of convergence or divergence of an infinite series =.
In probability theory and statistics, the Weibull distribution / ˈ w aɪ b ʊ l / is a continuous probability distribution. It models a broad range of random variables, largely in the nature of a time to failure or time between events. Examples are maximum one-day rainfalls and the time a user spends on a web page.
The report by property and real estate data firm ATTOM found that the portion of mortgaged homes that were seriously underwater rose slightly in the first quarter of 2024 from 2.6% to 2.7% of all ...
A sequence () that converges to is said to have order of convergence and rate of convergence if lim n → ∞ | x n + 1 − L | | x n − L | q = μ . {\displaystyle \lim _{n\rightarrow \infty }{\frac {\left|x_{n+1}-L\right|}{\left|x_{n}-L\right|^{q}}}=\mu .}
Those with accommodative insufficiency typically have PRA values below −1.50 diopters. See also. Accommodation in fish; Adaptation (eye) Amplitude of accommodation; Convergence insufficiency; Mandelbaum effect; Negative relative accommodation; References
A common form of exotropia is known as "convergence insufficiency" that responds well to orthoptic vision therapy including exercises. This disorder is characterized by an inability of the eyes to work together when used for near viewing, such as reading.
Divergence excess - exodeviation is more than 15 dioptres greater for distance than near deviation. Convergence insufficiency – near exodeviation greater than distance deviation. These can be due to nerve, muscle, or congenital problems, or due to mechanical anomalies.
