The eyex option causes margins to compute d log fd log x where f is the prediction function specified in the predict option of margins or if none was specified the default prediction option for the preceding estimation command. If you only have a regression output then you can still say something about the elasticity with its formula. In your case assuming there are no people with 0 age in your sample. At this point is the greatest weight of the data used to estimate the coefficient. LnQuantity c beta lnPrice Error After reading some marketing research papers it looks like the setup using 2 is favored for elasticity calculation. Elasticity and regression models.
To determine PQ we will use the mean Price 473 and mean Sales 2075.
The elasticity d log fd log x can be calculated easily from the marginal effect dfdx by using the chain rule. Along a straight-line demand curve the percentage change thus elasticity changes continuously as the scale changes while the slope the estimated regression coefficient remains constant. Plugging that into the formula gives. One way how to estimate the elasticity directly from the regression would be using log-log form for variables of interest. Elasticity and regression models. This price estimator has an R-Square of 91.
