Config file rate vs probability #276

Open JorySchossau opened 6 years ago

JorySchossau commented 6 years ago

The comments about mutation rates in the config files are incorrect, as rate assumes reference to a quantity per unit time, that quantity of which could be greater than 1. What we mean to say is 'probability'.

www.merriam-webster.com disagrees...

rate noun Definition of Rate (Entry 2 of 3) 1a : reckoned value : VALUATION b obsolete : ESTIMATION 2 obsolete : a fixed quantity 3a : a fixed ratio between two things b : a charge, payment, or price fixed according to a ratio, scale, or standard: such as (1) : a charge per unit of a public-service commodity

(2) : a charge per unit of freight or passenger service

(3) : a unit charge or ratio used in assessing property taxes

(4) British : a local tax

4a : a quantity, amount, or degree of something measured per unit of something else her typing rate was 80 words per minute b : an amount of payment or charge based on another amount specifically : the amount of premium per unit of insurance 5 : relative condition or quality : CLASS at any rate : in any case : ANYWAY

also, it can be greater than one. More than one mutation per site is probably not meaningful... but it could be.

JorySchossau commented 6 years ago

But we use it as a probability, so this is super confusing. We should stick to using either probability or rate (given some unit of change we are specific about).

But, if the mutation rate is .005, that means the rate of mutation is .005 per site or 1 mutation per 200 sites?

JorySchossau commented 6 years ago

The problem is that rate usually means per time. To take advantage of technicalities otherwise is confusing no matter how technically right it is. This is a useful discussion!
