void check_finite(const char *function, const char *name, const T_y &y)
Check if y is finite.
void check_bounded(const char *function, const char *name, const T_y &y, const T_low &low, const T_high &high)
Check if the value is between the low and high values, inclusively.
int bernoulli_rng(double theta, RNG &rng)
Return pseudorandom Bernoulli draw with specified chance of success using the specified random number...
