JV getting hard

I worked on the homework for tomorrow tonight and read chapter 5 in JV and had a hard time understanding it. I understood their syntax for the most part and the general concepts but when they started to go into a lot of formulas, I was lost. However I think that I understood the gist of what it was trying to teach although I am not sure I would use these techniques to actually process my own data.

F statistic

I finally understand what the F statistic means. Although I have been seeing in the output of SAS for the last year under the Proc GLM and I have had previous stats classes I never really got a clear explanation as to what it meant. Our lecture book made it very clear and used a great figure to explain in. I always knew you wanted a large F but now I know why.

Getting More Interesting

The class is starting to get more interesting now that we are starting to get into some more applied stats rather than theory or just defining term as much of that was review for me since i have already had a graduate level stats class. I am hoping to learn how to do hypothesis testing or find p value in R and learn different methods of finding this probability value.

Independant Study

I have been thinking about what I am going to do for my independent study. I have data from several Mangrove restoration experiments that I could use I am just not sure what to do with it. I have already done work on it using Proc GLM in SASS and have found means and sd's and graphed most of the data so I am not sure what kind of new manipulations I can do on it.

I have three experiments, one manipulating light level for seed establishment and seedling survival and growth, one manipulation elevation, therefore flooding regime in the field and one manipulation CO2 levels and salinities in the greenhouse, although this last dataset is not complete. This is the only data I have and should be able to use it. We will see what happens.

Hard To Blog

I am not very good at this blogging thing since I am not really a computer person and have trouble just writing a diary type composition. The class is going well and I hope to learn a lot that has practical applications rather than theory as many stats classes do. It seems that this is the direction the class is going in. I am looking forward to moving out of the baseline ideas and into more applied subjects.
