Error Specification In Transformed Models

  • Smallwood, David
  • Blaylock, James

Abstract

Autocorrelated residuals and a heteroskedastic error variance are both jointly and separately incorporated into a Box-Cox transformed model. A quarterly demand equation for pork is used for purposes of illustration. Results indicate that both functional form and error term specification play a crucial role in hypothesis testing and estimation of elasticities.
