Logarithmic, exponential, power and inverse regression
D Use the same key operations as for linear regression in order to call
in the results for these regression types.
D The regression equations for each regression type are listed below.
Logarithmic regression y = A + B * ln x
Exponential regression y = A * e
Bx
(ln y = ln A + Bx)
Power regression y = A * x
B
(ln y = ln A + B*lnx)
Inverse regression y = A + B * 1/x
