What we did this week:
For the lecture on Tuesday, we had a guest lecuture from Eric Berlow about Toads in Yosemite National Park, which is really helpful for me to learn about data gathering and applying statistic models. After taking 5 courses in STAT department, I have to say I'm still not confident enough to conduct statistical analysis on a real life problem. Even though I haven been given more than 10 projects in my precious classes, what I did was to do analysis using the required method on given dataset. So I never designed a survey or collected any data myself, nor did I ever doubt about the validity of the data I have. I learned a lot from Eric's experience on how they due with the lack of data.

For the lecture on Thursday, Professor Stark gave us a quick review/intro to hypothesis testing base on different models, which will be used in our earthquake project. I'm looking forward to practicing these methods in our project. When I took STAT 135, I felt hypothesis testing was hard, and I was wondering when I would actually use all those tests. After taking some more classes and doing a few more project, I hope I could take STAT 135 again because I realized that memorizing only the formula won't help me to solve a real life problem.

What I found challenging this week:
Definately I should have a quick review on what I learned in STAT134 and STAT 135, because I almost forget t-test, and I can't remember what a poisson process is. I hope we could have some more review on these concepts before staring on the project.

The other thing would be port setting. I wasn't able to make to Kristina and Chris's office hour on Friday. But the link below really helped me to solve this problem. Also as suggested in the link, we can simplely type localhost:7777 to access iPython in the browser rather than typing the ip of the VM. Still I wish to know about the details of how the port of guest and host work.

I learned a couple things that might be potentially useful for my other classes as well:

  1. The way to gather research data.
  2. The way to do hypothesis testing.
  3. Port setting.

Some links that has been useful for me:
This link is helpful for figuring out the right hypothesis testing model to use.
This is a good instruction on port setting.
