frml.additive.smooth: Formula for GAM without crossterms

Description

Creates a formula for gam to be used in regrXonS. For data $X=(X_1,...X_n,X_{n+1},...,X_m)$, variable to be regressed $X_{i}$, i=1...n and variables to regress on $S={X_{n+1},...,X_m}$ creates formula $X_i ~ s(X_{n+1}) + ... + s(X_m)$.

Usage

frml.additive.smooth(target.ind, pred.inds, var.str = "x")

Arguments

target.ind
integer, number for the variable to be regressed
pred.inds
integer(s), number(s) for the variable(s) on which we regress
var.str
name of variables used to create formula, default is "x"

Value

formula.additive.smooth() returns a formula $X_i ~ s(X_{n+1}) + ... + s(X_m)$
