CS475 Lab 4: Performance Evaluation

Objectives

This lab is intended to give you practice deriving polynomial and exponential equations from a set of observed data points based on what was discussed in the performance evaluation lecture.

Dataset

Use openoffice.org or any other plotting tool to analyze the data in data.ods.

Data.ods contains four columns: n, x, y, and z. The first column "n" is the independent variable. The other three columns represent the functions x(n), y(n), and z(n) where each row gives the function evaluated at a particular value of n.

Description

Derive equations in polynomials and/or exponentials for x, y, and z. If x is a polynomial function then it can be expressed as x(n) = a0*n^d + a1*n^(d-1) + ... + ad. If x is an exponential function then it can be expressed as x(n) = a*e^(bn). Finding the leading terms is sufficient.

See the Performance evaluation lecture for guidance.
