The following are some recommended conceptual self-assessment questions for the lesson called Do you really understand what functional modeling is?. They’re intended for you to work through to test your own understanding of the key concepts we covered there.

Question 1

a) Which is a random stochastic variable:  \mathbf{l}_{meas}  or  \mathbf{l}_{true}? And why?

b) In these topics on functional modeling, I speak a lot about how  \mathbf{l}_{true}  is what the measurements would be if they were error free. Can you briefly explain this?

c) In a few succinct sentences, summarize why functional modeling is important and what it does for us in the bigger picture. In thinking this through you might refer to the ‘Big Picture View’ we discussed in class.

Question 2

What is a parametric functional model? Keep it simple but summarize what characteristics distinguish that kind of model, and/or how you know when you’re looking at a model of that form.

(You know enough to answer this now but you might also want to revisit it after doing the next lesson on the different kinds of models, since it puts the parametric model into context and discusses how it is different from the other forms.)

Other related questions you’ve already done

You might recall that we also did some conceptual self-assessment work on the basics of functional modeling when we did the topic called Some Fundamentals and the Three Key Math Models for Geospatial Applications, e.g. in the questions found here. No need to re-do those for handing in, but you might find it useful to look them over again and compare what you know now to what you knew then.

If you’re one of my students, then you’re expected to answer these on your own and submit them according to the directions provided in class, i.e. you don’t  need to submit them through this website. Don’t forget that our TA and I are both here to help you in the associated lab (and/or tutorial) sessions.

I want you to put your answers to these conceptual questions into a single document. I don’t mind if you hand write it or type it out – do what works best for you.

But I want you to use the same document for all of the self-assessment questions you do before the due date, i.e. you will be asked to hand them all in together. This means you should keep things well organized with clear headings so you (and your TA) can figure out which solutions refer to which questions. Good self-assessment documents use headings and some even provide the links, e.g. the URL for this page. This helps you keep track and go back and forth quickly between the problems and solutions.

Also, keep in mind that you will be asked to submit them through D2L, so you’ll have to scan any handwritten documents.
