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 G.
My example indicates that the log odds for A is +1.16 and T is -0.22. I am not able to duplicate this result. Can you explain the steps calculate the log odds from these probabilities?
The funny part is that I am good at individual subjects like Probability by itself or logs by itself So who was the genius who came up with log odds?
