Homework 1
- Due April 12 (Monday).
- Here is the problem set for homework 1
and R code (hw1.R) for Problem 1.
- For problem 2 (b), note that interpSpline requires at least
four knots to be specified as it calls splineDesign function, which
needs at least four knots for cubic splines. Just for plotting,
add 0 and 4 to x as boundary knots
and the values of the interpolating spline function at 0 and 4
(from your solution) to y and use interpSpline function.
- For those who have not used R before, read
