unexported functions to support fast calculation of the stratification pattern with fastSP and fastSP.k

Description

unexported functions to support fast calculation of the stratification pattern with fastSP and fastSP.k

Usage

nrt.wt(v)

nrt.wtx(x, s, el)

nrt.dist1(x, y, s, el)

nrt.dist(x, y, s, el)

soa.contr(s, el = 1)

soa.kernel(s, el, y)

EDy(D, s, y = 0.01, kernel = soa.kernel)

nrt.kernel(s, el)

Rd.kernel(s, el, y)

EDz(D, s, y = 0.01)

Arguments

v	row vector of a full factorial
x	row number of a full factorial in k q-level columns, or vector of such numbers
s	the base for s^el levels
el	the power for s in s^el levels
y	row number of a full factorial in k q-level columns, or vector of such numbers; or an arbitrary number (in soa.kernel, EDy, Rd.kernel)
D	design with m columns in s^el levels
kernel	type of kernel
