I am trying to learn more of the Arithmetic method of compression. So

I laid this model to myself....

I have a 2 in 14 chance to have a compressible result, and a 12 in 14

chance of having a non-compressible result. Statistically speaking of

course. Now I figure the cost to determine will be higher than the

compression saved, I am now convinced of the 'no random recursive

compression' plan... but I am trying to create a basis to do some

compression models, but I am having a hard time with arithmetic

compression.

Would I use a similar to huffman method to determine if I have

compression?

When I do that I have two odds, 1 or 0. There are 4 outcomes. I take

the percentages of 1+1 * 3, 1+0 * 3, 01 *2 and 00 *1 and divide all

four results to get the compression (Or size increase) of the simple

huffman. If this is the way this math is calculated then that is easy

enough. But is there alternatives? I feel like I am missing something

here...
