Query: Minimum Hellinger distance estimates for a periodically time-varying
  long memory parameter   We consider a purely fractionally deferenced process driven by a periodically
time-varying long memory parameter. We will build an estimate for the vector
parameters using the minimum Hellinger distance estimation. The results are
investigated through simulation studies.
