Quasi Skewed Truncated Normal Generator

qstrandn - Quasi Skewed Truncated Normal Generator

qstrandn samples n data points following three types of normal distributions and their combinations:

• QUASI NORMAL: normal distribution elevated to the power of c
• SKEWED NORMAL: normal distribution with skewness alpha
• TRUNCATED NORMAL: normal distribution truncated at lower limit l and upper limit u

% x=qstrandn(n,mu,sigma,c,alpha,l,u)

% OUTPUT
%   x=sampled data
% INPUT
%   n=number of samples
%   mu=mean (default: 0 --> standard Gaussian distribution)
%   sigma=standard deviation (default: 1 --> standard Gaussian distribution)
%   c=coefficient of quasi-normality (default: 1 --> Gaussian distribution)
%   alpha=skewness (default: 0 --> not-skewed distribution)
%   l=lower limit of truncation (default: -inf --> no lower truncation)
%   u=upper limit of truncation (default: inf --> no upper truncation)
