Specific Problems

Palm 6.9

• Part of the goal here is to see that while, mathematically, "more is better," having a higher order may not make much of an improvement. The key is to figure out the "just right" order where adding terms make important changes in how the model predicts the values.
• You can use polyfit and polyval to get the coefficients and estimates.
• Don't forget to have the \(S_t\) value somewhere!

Palm 6.16

• This problem is a straight-forward general linear regression.
• If you want, you can use the General Linear Regression Example Code or you can start from scratch. If you use the example, be sure to use the appropriate version of the honor code.

Chapra 15.7

• This is a multidimensional general linear fit.
• If you want, you can use the General Multidimensional Linear Regression Example Code or you can start from scratch. If you use the example, be sure to use the appropriate version of the honor code.
• Don't forget to calculate the required estimate and error in that estimate!

Chapra 15.10 Alternate

• These are both general linear regressions.
• If you want, you can use the General Linear Regression Example Code or you can start from scratch. If you use the example, be sure to use the appropriate version of the honor code.
• Be sure you create two graphs for each piece - one for the total population and one with the three populations shown separately.
• Also be sure to answer all the questions.

Chapra 15.12

• This problem requires a general linear fit method to solve for the coefficients.
• If you want, you can use the General Linear Regression Example Code or you can start from scratch. If you use the example, be sure to use the appropriate version of the honor code.
• Be sure to include the statistical information and the estimates in the lab report.

Chapra 15.11

• This program requires nonlinear regression to solve.
• If you want, you can use the Nonlinear Regression Example Code or you can start from scratch. If you use the example, be sure to use the appropriate version of the honor code.
• Be sure to include your discussion.

Chapra 15.14(b)

• This program requires nonlinear regression to solve.
• If you want, you can use the Nonlinear Regression Example Code or you can start from scratch. If you use the example, be sure to use the appropriate version of the honor code.
• Be sure to include your discussion.
