Here are some properties of the ΦΦ function that can be shown from its definition. limx→∞Φ(x)=1,limx→−∞Φ(x)=0limx→∞Φ(x)=1,limx→−∞Φ(x)=0; Φ(0)=12Φ(0)=12; Φ(−x)=1−Φ(x)Φ(−x)=1−Φ(x), for all x∈Rx∈R....
Thus asymptotic normality (μa,σa2) is equivalent to convergence in distribution of (Ta - μa)/σa to a standardized normal random variable. Obviously, asymptotic normality (μn,σa2) is equivalent to the same property with (μa*,σn*2), if (3)σa*/σa→1,(μa*−μa/σa→...
DefinitionLet be a continuous random variable. Let its support be the whole set of real numbers: Let and . We say that has anormal distributionwith mean and variance if and only if its probability density function is We often indicate the fact that ...

Definition Let be a continuous random vector. Let its support be the set of -dimensional real vectors:Let be a vector and a symmetric and positive definite matrix. We say that has a multivariate normal distribution with mean and covariance if its joint probability density function is ...
By definition, the lognormal distribution is the discrete and ongoing distribution of arandom variable, the logarithm of which is normally distributed. In other terms, lognormal distribution follows the concept that instead of having the original raw data normally distributed, the logarithms of this ...
