In np: Nonparametric Kernel Smoothing Methods for Mixed Data Types

np 0.70-1

• The default multistart cap for bandwidth selection now follows min(2, p) across the core estimator families, replacing the older min(5, p) cap. This includes automatic LP degree-search calls when search.engine="nomad" or "nomad+powell" and nmulti is not supplied explicitly.
• The univariate boundary density helper npuniden.boundary() now defaults to nmulti=1.
• The empirical studies supporting this change are documented under benchmarks/validation/.
• LP-capable front ends now accept nomad=TRUE as a documented convenience preset for the recommended automatic NOMAD local-polynomial route. Missing settings expand to the same long-form LP/NOMAD defaults documented in the bandwidth help pages, and regression formula calls such as npreg(y ~ x, nomad = TRUE) now carry that shortcut through the internally computed bandwidth path.
