observed {validann}

Return observed target values.

Description

Return observed target values used for fitting ‘ann’ or ‘nnet’ ANN models.

Usage

observed(object)

Arguments

object

an object of class ‘ann’ as returned by ann or of class ‘nnet’ as returned by nnet.

Details

This function can be invoked by calling observed(x) for an object x of class ‘ann’ or ‘nnet’.

Value

a 1-column matrix of observed target values.

Examples

# Get observed values of y used to train ann object `fit'.
# ---
data("ar9")
samp <- sample(1:1000, 200)
y <- ar9[samp, ncol(ar9)]
x <- ar9[samp, -ncol(ar9)]
x <- x[, c(1,4,9)]
fit <- ann(x, y, size = 1, act_hid = "tanh", act_out = "linear", rang = 0.1)
y_obs <- observed(fit)
