**Data Entry**
The data has 2 columns separated by spaces or tabs. Col 1 is the x or independent
variable, and col 2 is the y or dependent variable. Data from each subject is in its own row.

Two power parameters for the polynomial fit are provided, one for the mean, the other for
variance. Please note that power must be less than the number of rows, and
capped at 5 for mean and 3 for variance. Curve firtting beyond the third
power for mean and second power for variance have little practical meaning in the bio-medical domain.

The percentage confidence interval defines the higher and lower curves which represent percentage confidence interval of the curve fit
