  We provide a robust and generic method to assess the screening properties and
extract the scaling exponents of quasiparticle edge excitations of quantum Hall
states from model wavefunctions. We numerically implement this method for the
fundamental quasihole and hole excitations of several model states. For the
Laughlin, Moore-Read, and Z_3-Read-Rezayi states, we find agreement with the
predicted edge theory, verifying the bulk-edge correspondence. We also use this
to obtain the first clear microscopic demonstration of the pathologies of the
Gaffnian wavefunctions.
