k Power Regression Graph
Exponential regression expresses y as a proportion of the power of x. The standard
power regression formula is y = a % x
b
, so if we take the logarithms of both sides we
get logy = loga + b % logx. Next, if we say X = log x, Y = logy, and a = loga, the
formula corresponds to linear regression formula Y = a + bX.
