This paper was written for my Numerical Analysis class. It was a small project in which I had to write a code and also answer a real world problem. One of the problems I face as an aspiring economist is finding appropriate data to run regressions on. If the data does not have the same time frequency, the model is meaningless. Hence, I wrote a code for Cubic Spline Interpolation and showed it accurately interpolates data.
The paper requires a bit of mathematical maturity, but the idea can still be clearly understood.
Note: I did not include any of the appendices, and the format of the paper was altered when I turned it into a PDF for some reason.
