At this point is the greatest weight of the data used to estimate the coefficient. You can calculate the elasticity using the formula. Mathepsilon frac bY Xfrac X Y b math Depending on your regression equation the elasticity is therefore either the estimated coefficient double log the coefficient multiplied divided by the left-hand variable linear-log multiplied by the right-hand variable log-linear or the fraction of. This price estimator has an R-Square of 91. LnQuantity c beta lnPrice Error After reading some marketing research papers it looks like the setup using 2 is favored for elasticity calculation.

If you have the data then you can just run the regression in logs as Wenai suggested.
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. The elasticity d log fd log x can be calculated easily from the marginal effect dfdx by using the chain rule. Going back to the demand for gasoline.
