clear

Clear any previously set local pilot bandwidth.s

plth =arg (default = “cv”)

Pilot bandwidth method: simple rule-of-thumb (“rot”), robust rule-of-thumb (“rotr”), residual squares criterion (“rsc”), modified multi cross-validation (“cv”), user-defined (“user”).

pltbw=arg (default =1)

User-defined bandwidth (if “plth=user”).

plthmin=arg (default = 0.1)

Bandwidth grid search minimum value (if not “plth=user”).

plthmax=arg (default =1)

Bandwidth grid search maximum value (if not “plth=user”).

plthlen=integer (default = 100)

Bandwidth grid search length (if not “plth=user”).

plthinc=integer (default = 10)

Bandwidth grid search increment step percentage increase (if not “plth=user”).

plthcup=integer (default = 10)

Stop rule: consecutive increases of objective function before stop (not available when “plth=user”).

pltm=arg (default = 10)

Modified multifold CV m-value: percentage of sample size used in bandwidth determination (when “plth=cv”).

pltq=integer (default = 4)

Modified multifold CV Q-value: percentage of sample size used in bandwidth determination (when “plth=cv”).

auxk=integer (default = 2)

Estimation polynomial degree for pilot stage in excess of final stage degree. This number should always be an even positive integer.
