Rivet::rand01
double rand01()
Return a uniformly sampled random number between 0 and 1.

Rivet::pCrystalBall
double pCrystalBall(double x, double alpha, double n, double mu, double sigma)
Probability density of a Crystal Ball distribution at x.

Rivet::pNorm
double pNorm(double x, double mu, double sigma)
Probability density of a Gaussian/normal distribution at x.

Rivet::randnorm
double randnorm(double loc, double scale)
Return a random number sampled from a Gaussian/normal distribution.

Rivet::randcrystalball
double randcrystalball(double alpha, double n, double mu, double sigma)
Return a random number sampled from a Crystal Ball distribution.

Rivet::randlognorm
double randlognorm(double loc, double scale)
Return a random number sampled from a log-normal distribution.

Rivet::rng
std::mt19937 & rng()
Return a thread-safe random number generator (mainly for internal use)
