Those patients with severe white matter injury typically exhibit more extensive signs of brain damage. Infants with severe PVL suffer from extremely high levels of muscle tone and frequent seizures. Children and adults may be quadriplegic, exhibiting a loss of function or paralysis of all four limbs.
The initialism PVL may refer to: The paleontological collection of the Fundación-Instituto Miguel Lillo, Universidad Nacional de Tucumán; Parameter Value Language, the data markup language, used by NASA; Panton–Valentine leukocidin, a factor in bacterial virulence; The Pascack Valley Line, a commuter rail line operated by NJ Transit
Given a sample from a normal distribution, whose parameters are unknown, it is possible to give prediction intervals in the frequentist sense, i.e., an interval [a, b] based on statistics of the sample such that on repeated experiments, X n+1 falls in the interval the desired percentage of the time; one may call these "predictive confidence intervals".
1871 and 1872 also saw the emergence of a new approach in textology, namely, publishing the PVL as a separate text rather than as part of another chronicle. [9] Those years, lithographic versions of the Hypatian and Laurentian texts of the PVL were published, although both titles claimed to represent "the" Povest' vremennykh let. [9]
Conversely, given i.i.d. normal variables with known mean 1 and unknown variance σ 2, the sample mean ¯ is not an ancillary statistic of the variance, as the sampling distribution of the sample mean is N(1, σ 2 /n), which does depend on σ 2 – this measure of location (specifically, its standard error) depends on dispersion.

In statistics, truncation results in values that are limited above or below, resulting in a truncated sample. [1] A random variable y {\displaystyle y} is said to be truncated from below if, for some threshold value c {\displaystyle c} , the exact value of y {\displaystyle y} is known for all cases y > c {\displaystyle y>c} , but unknown for ...
The Pacific View League (PVL) was a high school athletic conference in California affiliated with the CIF Southern Section. The league was formed in 1998, [ 1 ] [ 2 ] pulling Camarillo and Channel Islands high schools from the Marmonte League to join Hueneme , Oxnard , and Rio Mesa highs from the Channel League .
