I am trying to get the standard deviation for an array like this:
//put all GW1 records into an array $GW1pluck_array = $results->pluck('GW1')->toArray(); //get standard deviation for all GW1's in the array $GW1std = stats_standard_deviation($GW1pluck_array);
stats_standard_deviation does not exist as a laravel function. Is there any such function I can use? Package I can install?
