I have a log-log model as follows:
ln quality = ln price + predictor_2 + predictor_3
I ran a regression and using the coefficient values obtained, I predicted log quality values and then I plotted a curve of predicted log quality (y-axis) vs. log price (x-axis). I feel it is better to have a plot of predicted quality vs. price (instead of the log of these variables). Can I use the same coefficients obtained from the log-log model regression to predict quality using price (note: not the log of price), predictor_2 and predictor_3 values? Or should I apply some conversion formula to obtain different coefficient values for the independent variables?
