Predict GMDH Combinatorial

Description

Calculates GMDH Combinatorial model predictions for new data.

Usage

## S3 method for class 'combi'
predict(object, newdata, ...)

Arguments

object

an object of class 'combi'

newdata

matrix containing dependent variables in the model, wich the predictions are calculated.

...

other undocumented arguments

Value

A matrix with predictions.

Examples

set.seed(123)
x <- matrix(data = c(rnorm(1050)), ncol = 3, nrow = 350)
colnames(x) <- c("a", "b", "c")
y <- matrix(data = c(10 + x[, "a"] + x[, "b"]^2 + x[, "c"]^3), ncol = 1)
colnames(y) <- "y"
x.test <- x[1:10, ]
y.test <- y[1:10]
x <- x[-c(1:10), ]
y <- y[-c(1:10)]

mod <- gmdh.combi(X = x, y = y, criteria = "PRESS")
pred <- predict(mod, x.test)
summary(sqrt((pred - y.test)^2))
