Query: Emanuel Parzen: A Memorial, and a Model With the Two Kernels That He
  Championed   Manny Parzen passed away in February 2016, and this article is written partly
as a memorial and appreciation. Manny made important contributions to several
areas, but the two that influenced me most were his contributions to kernel
density estimation and to Reproducing Kernel Hilbert Spaces, the two kernels of
the title. Some fond memories of Manny as a PhD advisor begin this memorial,
followed by a discussion of Manny's influence on density estimation and RKHS
methods. A picture gallery of trips comes next, followed by the technical part
of the article. Here our goal is to show how risk models can be built using
RKHS penalized likelihood methods where subjects have personal (sample)
densities which can be used as {\it attributes} in such models.
