cubic: A Data Set for the Example of the Qprog Function
Description
This data set is used for the example of the qprog function. Format
A data frame with 50 observations on the following 2 variables.
x- The predictor vector.
y- The response vector.
Source
STAT640 HW 14 given by Dr. Meyer.Details
We use the qprog function to fit a constrained cubic to this data set. The constraint is that the true regression is increasing, convex and nonnegative.
