Logarithmic regression
• The regression formula is y = A + B•Inx. Enter the x data
as the logarithm (In) of x, and the y data inputs the same
as that for linear regression.
• Estimated values ,and based on the regression
formula can be calculated using the following formulas:
• The same operation as with linear regression can be used
to obtain the regression coefficient and for making
corrections. To obtain the estimated value ,
x
, Is used, and to obtain estimated value , y
, is used.
Furthermore,
∑
x,
∑
x

and
∑
xy are obtained by
∑
Inx,
∑
(Inx)
2
, and
∑
lnx•y respectively.
