onls (version 0.1-1)

y0: y0-values from orthogonal nonlinear least squares regression

Description

Returns the ${\color{red} y_{0i}}$ values as obtained from minimizing the Euclidean distance $$\min\| D_i \| \equiv \min\sqrt{(x_i - x_{0i})^2 + (y_i - {\color{red}y_{0i}})^2}$$

Usage

y0(object)

Arguments

object

an object returned from onls.

Value

• A vector of $y_{0i}$ values.

encoding

latin1

Examples

DNase1 <- subset(DNase, Run == 1)
DNase1$density <- sapply(DNase1$density, function(x) rnorm(1, x, 0.1 * x))
mod <- onls(density ~ Asym/(1 + exp((xmid - log(conc))/scal)), 
             data = DNase1, start = list(Asym = 3, xmid = 0, scal = 1))
y0(mod)
