Bring on the Ren Fest!

In a week that is.

I've been working on hats and shirts for Keagan and Cassidy. Not all of my attempts have been close.

But I've got down the patterns and I've got the shirts almost done and hats half cut out. :) Here she is practicing a pirate face (how horrible!) in one of the pre-hats.


I also made Keagan and crinkle toy shaped like a normal distribution.


I'd also like to point out Shannon's shirt in this picture. :)

And she just got her 4 month shots! Woo hoo! Way to celebrate the 4 month mark. :) She was pretty good with them. Cried for about 2 minutes, then calmed down and fell asleep. What a wonderful child. How lucky we are.

Resources Not Available

I've been in my office since about 11:00am today, and it's just about 9:00pm now. For as much SAS as I've ran, I don't have much done. Explaining why will somewhat support the name of this blog.

I'm generating normal data that is representing data from an experiment. In the experiment they start with right skewed data, take the log10 transformation of it, and then end with normal data.

So what I thought I needed to do was make normal data, exponentiate it base 10, then I'd have the skewed data. But my major professor says I need to exponentiate it base e. She said, we are assuming the skewed data is lognormal. This means that we are assuming if we exponentiate it base e it will be normal, and this is just because of what it means to be lognormal. When I don't see it.

Wikipedia says the base doesn't matter. But Shannon's theory book is locked in his office so I can't check that. I guess I just don't care anymore. I'll just do what she says and then be done with it. I am so tired of looking at this stuff and hoping that its right. I just won't hope anymore.
