Double Gauss curve function for nlme

Description

Double Gauss function used in fitting nlme curve for observations

Usage

doubleGauss(dat, y, time, params = NULL, concave = TRUE, ...)

Arguments

dat	subject data to be used
y	outcome variable, character vector
time	time variable, character vector
params	NULL unless user wants to specify starting parameters for gnls
concave	Boolean
...	just in case

Details

User should only have to worry about setting concavity of this function

y ~ (time < mu) * (exp(-1 * (time - mu) ^ 2 / (2 * sig1 ^ 2)) * (ht - base1) + base1) + (mu <= time) * (exp(-1 * (time - mu) ^ 2 / (2 * sig2 ^ 2)) * (ht - base2) + base2)
