(PECL stats >= 1.0.0) Not documented float stats_stat_binomial_coef ( int $x, int $n ) Parameters: x n Returns: This function is currently not documented; only its argument list is available.

(PECL stats >= 1.0.0) Returns the standard deviation float stats_standard_deviation ( array $a [, bool $sample = false ] ) Parameters: a The array of data to find the standard deviation for. Note that all values of the array will be cast to float. sample Indicates if a represents a sample of the population; defaults to FALSE.
