PredY Returns the predicted Y for a given x.

PredY(mode, x, parameters)

• Mode governs the regression model used:

1 y= sl*x+int

2 y= sl*ln(x)+int

3 y= int*exp(sl*x)

4 y= int*x^sl

5 y= int*sl^x

6 y= sl/x+int

7 y= L/(1 + a*exp(b*x))

8 y= a*sin(b*x+c)+d

9 y= cx^2+bx+a

10 y= dx^3+cx^2+bx+a

11 y= ex^4+dx^3+cx^2+bx+a

• Parameters is either one argument (a list of the

coefficients of the regression line), or the n coefficients

one after another.

PredX Returns the predicted x for a given y.

PredX(mode, y, parameters)
