The LSRL after an exponential transformation is log ŷ = 1.245 + 0.357x. What is the exponential form of the regression?

Answer 1

Typically, LSRL log fit uses natural logarithm (TI-84 uses it, Matlab uses it). Based on that, the exponential form is y = e^{1.245 + 0.357x}

This can be simplified:

y = e^{1.245 + 0.357x}

y = (e^1.245)(e^0.357x)

y = 3.4729e^0.357x
