PsiMetalogfit(num_coef, x_values, y_values)

PsiMetalogFit() computes 2 to 10 coefficients for PsiMetalog() by fitting m pairs representing a CDF.  Enter this function as an array formula.  

Example:  The formula {=PsiMetalogFit(5, A2:E2, A1:E1)} is array entered into cells A3:E3 where the Y_values are contained in cells A1:E1 and the X_values are contained in cells A2:E2.

A1 = 0.010, A2 = 10

B1 = 0.100, B2 = 22

C1 = 0.500, C2 = 33

D1 = 0.900, D2 = 43

E1 = 0.990, E2 = 50
