Analysis 4

In this tutorial you will work through an example linear fit. The example is the trajectory experiment described in the previous tutorials. In this model we had altitude data <math>d_i</math> taken at times <math>t_i</math> that was modeled with a quadratic formula:

<math> d_i = a t_i^2 + b t_i + c </math>.

The following example is carried out using the python programming language. A great collection of python tools are downloadable for free (since you are students) here: [1]

Here is a file with the altitude data: media:Altitudes.txt;

Code (change suffix to .py) media:Linear_model.txt; Output media:Data_linear.png media:Data with model linear.png
