Question

The lsrl after an exponential transformation is log yhat=.4785 + 1.468x. What is the exponential form of the regression?

Answer 1

`10^(0.4785+1.468x)=y`

Explanation:

So I'm assuming when you typed "log yhat=.4785 + 1.468x", you meant to write:
`log(y)=0.4785+1.468x`. And generally a logarithm can be written in the form
`log_ba=c` which can then be rewritten as
`b^c=a`, but since the log has no base, it's assumed to be 10. So in this case you have the equation:

`log_(10)y=0.4785+1.468x`, which can then be written in exponential form as:

`10^(0.4785+1.468x)=y`
