Logarithmic Regression Graph
Logarithmic regression expresses
y
as a logarithmic function of
x
. The standard logarithmic
regression formula is
y
=
a
+
b
×
In
x
, so if we say that X = In
x
, the formula corresponds to
linear regression formula
y
=
a
+
b
X.

Exponential Regression Graph
Exponential regression expresses
y
as a proportion of the exponential function of
x
. The
standard exponential regression formula is
y
=
a
×
e
bx
, so if we take the logarithms of both
sides we get In
y
= In
a
+
bx
. Next, if we say Y = In
y
, and A = In
a
, the formula corresponds
to linear regression formula Y = A +
bx
.
