Exponential / Power regression HELP!!!!

Exponential / Power regression HELP!!!!

Exponential / Power regression HELP!!!!

(OP)

Expo Equation: y = c *e ^(b * x)

Does any one know how to calculate c and b for a given set of X and Y values?? When I do trend line in excel, it automatically calculates the value for me. However, if I want to code in ASP/VB I need to know how excel arrive with the values for c and b when X and Y are given.

Power Equation: y=c*x^b

TIA

RE: Exponential / Power regression HELP!!!!

Transform the equations by taking LN or LOG of the variables:

LN(y)=LN(c)+ b*x
and
LN(y)=ln(c)+ b*LN(x)
