The probability is sometimes written to distinguish it from other functions and measure P so as to avoid having to define "P is a probability" and () is short for ({: ()}), where is the event space and () is a random variable. Visa mer Probability theory and statistics have some commonly used conventions, in addition to standard mathematical notation and mathematical symbols. Visa mer The α-level upper critical value of a probability distribution is the value exceeded with probability α, that is, the value xα such that F(xα) = 1 − α where F is the cumulative distribution function.
