exp2d.rand: Randomly subsampled 2-d Exponential Data

Description

A Random subsample of data(exp2d)

Usage

exp2d.rand()

Value

• Output is a list with entries:
• X
  2-d data.frame with 80 input locations
• Z
  Numeric vector describing the responses at the X locations
• XX
  2-d data.frame with the remaining 361 input locations

Details

Data is subsampled without replacement from data(exp2d). Of the 80 input/response pairs X,Z, 50 are taken from the first quadrant, i.e., where the response is interesting, and the remaining 30 are taken from the other three quadrants
