[Biojava-l] Distributions over infinite Alphabets

Hi -
 
Currently you can make a Distribution over (for example) the Double alphabet and you can train it or assign a weight to a value (eg the probability of the 2.0 Symbol could be set to 0.5).
 
Can anyone think of a way to represent a probability density as a Distribution? For example you may want to set the probability of seeing a value between 0 and 1.0 to be 0.8. This is a bit tricky as there are an infinite number of values between 0 and 1.0 and the value of getting exactly 0.237865765 would be infinitely small.
 
Would this best be represented using something other than a Distribution?
