Goal: Develop a program that determines the best fit between various regression types (the first six: Linear, Logarithmic, Exponential, Power, Exponent, Inverse).
However, I am getting the same correlation for each of the types. Here is the code (FW 7820):
Advice?

LOCAL clist,k,m,p,c;

C2:=ylist;
S1(1):='C1';
S1(2):='C2';
CHECK(1);
clist:={};

FOR k FROM 1 TO 6 DO
S1(4):=k;
Do2VStats(S1);

END;
//find and display results

RETURN clist;
END;
