Palatal rugae in population differentiation between South and North Indians: A discriminant function
Since the dependent variable is split in two categories, one discriminant function
is estimated with one categorical dependent and seven independent variables.
According to the equation, the discriminant function
score for any set of measurements that is above the cut score is probably for a male individual whereas a score that was below the cut score is probably for a female subject.

The results showed that two statistically significant discriminant functions
were formed: Wilks' lambda = 0.044, [X.sup.2] = 86.010, df = 16, and p value = 0.000 for the first function and Wilks' lambda = 0.308, [X.sup.2] = 32.403, df = 7, and p value = 0.000 for the second.
For training samples with capacity [n.sub.i] from totality [G.sub.i] (where [alpha] = 1,2, ..., [n.sub.i]; I = 1,2, ..., m), all training samples were successively substituted into the established discriminant function
and the corresponding criterion was used for water source recognition.
The significance test of the discriminant function
are shown in [Table 4], Wilks' ?' value was 0.530, Chi-square value was 137.535, so the discriminant result was proved to be effective.
Punniyamoorthy and Thoppan (2012a) have tested for the assumptions governing the use of the Linear Discriminant Function
. The assumptions are that the data should be normally distributed (verified using the Q-Q Plot) and that the two groups should have equal variance-covariance matrices (tested using the Box's M Test).
A linear discriminant function
, y(x), that can reduce the data to a one-dimensional numerical value is determined:
