Cleaned up npsigtest, reverted to alternative method for imposing the
null based on uocquantile() and evaluation data. Corrected error in
Rademacher weights setting for the wild-bootstrap (was not using
Rademacher weights)
Added pivot option, cleaned up
Updated np.sigtest.Rd for addition of power and added joint test to
the mix. Testing required.
Cleaning up doc np.sigtest.Rd
Cleaning up summary i/o
Adding some error checking for joint test/index
Modded header description
Cleaning up descriptions, particularly for the new joint option
Added comment on nature of pivoting
Added instructions for OS X users who have not installed Xcode
Adding details to npsigtest regarding being oversized for Type I in
small sample settings
Clarifying details
Corrected glitches when measure zero event that probabilities are
identical for all choices occurs in npconmode
Updated instructions with info for installing the development version
of npRmpi
Added constrained.R to demo to demonstrate constrained estimation
using the approach of Du, Parmeter and Racine (2013).
Cleaning up constrained illustration
Elaborating on the constrained demo, added local polynomial regression
from the function npglpreg() in the crs package.
Added consistency check for lower and upper bounds in constrained demo.
Using chol2inv(chol()) for inverting symmetric matrices (faster than solve())
Using chol2inv(chol()) further in np.singleindex.R, arguments not
being passed to npksum() in npregiv.R and npregivderiv.R, consistent
spelling in util.R
