calculateQTest function
Returns a DixonResults object representing the result of Q test calculation
Throws a DixonException if 'n' is or got lower than 3 during the calculation
Implementation
DixonResults calculateQTest(List<double> values, Confidence confidence) {
// Prepares values before calculation
var filteredValues = values.toSet().toList();
filteredValues.sort();
filteredValues.length < 3 && (throw DixonException('n is lower than 3'));
filteredValues.length > 30 && (throw DixonException('n is greater than 30'));
return _calculateQTest(
filteredValues, DixonResults(confidence, filteredValues));
}
