Hi really hope someone can help i need to fit a linear regression model to this trans formed data (it has been transformed by log(original+1)
I then need the equation of the model - i Have worked this out to be log y = 0.0272 + 0.9761(logx+1) - i think this is wrong!!!!
The question is then asking me to take exponentials of both sides of the fitted equation (remember that e^(a+b log(x+1)) = c(x+1)^b, where c=e^) and re express the model directly for the second column in terms of the first.
Giving a very sibple equation relating column 2 to column 1
