If the value is greater than the BMI 23, there will be more heavily than the criteria (Y = 1) BMI values less than equals 23, there will be no more heavy than the criteria (Y = 0) .
If the BMI by more than 23 will be directed too hard criteria (Y= 1), if the value BMI less than equal to 23 will not have a bow too hard criteria (Y= 0)
