In thozh912/Lab7: Ridge regression and data munging package

Description Usage Arguments Value See Also Examples

A method that prints out the fitted values of the ridge regression model, possibly for new data.

1 2	## S3 method for class 'ridgeregr' predict(x, x_values = "default")

`x`	A ridgeregr object.
`x_values`	Optional. If included, the predictions are made on these x_values instead.

a numeric vector of fitted values.

predict. The generic function from which predict.ridgeregr is created.

a <- ridgeregr(Petal.Length~Sepal.Width+Sepal.Length, data=iris, lambda=10)
predict(a) # The fitted values
df <- data.frame(Petal.Length=runif(n = 150, min = -1.5, max = 1.5), x2=runif(n = 150, min = -2, max = 2.5),x3 = runif(n = 150, min = -1.5, max = 1.5) )
predict(x=a, x_values = df) # Predicted on the new x-values in the df data.frame.
