I am trying to understand the calculation of log odds. I'm provided with the following example: 4 out of 5 are A or a .80 probability and 1 out of 5 are T or .20. The possible values are A,T,C or
My example indicates that the log odds for A is +1.16 and T is -0.22.

zplane - don't the zeros and poles need to be complex?
1 Answer
Accepted answer
zplane is a little subtle. When B and A are rows, they represent transfer functions. However, if B and A are columns, they are zeros and poles.
[b,a] = ellip(4,.5,20,.6);

The Higgs Field
You simply can't travel to the outside. No matter what you do, you're going down the r-coordinate with the same certainty as you climb up the t-coordinate outside the EH.
