Exponential regression
• The regression formula is y = A•e
B•x
(Iny = InA + Bx).
Enter the y data as the logarithm of y(ln), and the x data
the same as that for linear regression.
• Estimated values , and based on the regression
formula can be calculated using the following formulas:
• Correction is performed the same as in linear regression.
Constant term A is obtained by
,
estimated value is obtained by x
, and estimated value is obtained by
y
.
∑
y,
∑
y
2
and
∑
xy are obtained by
∑
Iny,
∑
(Iny)
2
and
∑
x•Iny respectively.
