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.

Template metaprogram to calculate whether a summand needs to be included in a proportional (log) prob...
size_t max_size(const T1 &x1, const T2 &x2)
int size(const std::vector< T > &x)
Return the size of the specified standard vector.
void check_greater(const char *function, const char *name, const T_y &y, const T_low &low)
Check if y is strictly greater than low.
VectorView is a template expression that is constructed with a container or scalar, which it then allows to be used as an array using operator[].
void check_consistent_sizes(const char *function, const char *name1, const T1 &x1, const char *name2, const T2 &x2)
Check if the dimension of x1 is consistent with x2.
