Generates pseudo-random numbers from a symmetric triangular distribution.
rtri(n, r)
Returns a vector of n independent random variables generated from a symmetric triangular distribution with mean direction 0 and concentration parameter r.
number of random variables to generate.
concentration parameter of the distribution. r must be between 0 and \(4/pi^2\).
The triangular cdf is inverted to obtain the random numbers.
