Re: some probability 101 help (will give $)
[ QUOTE ]
1 I guess they mean exponential distribution with parameter 5 (gamma has 2 parameters). Then mean =1/5 mode = 0 median = 0.693/5=0.1386 exponential [/ QUOTE ] mean is 5 median is you solve by integrating the density function of a gamma distribution. in this case e^(-y/5)/5 which will give us a probability. you integrate this from 0 to y and make it equal to .5 because it is the median. Median is (half of the probability distribution). I believe that's how it works. Mode is 0 that is correct. |
