The sample mean is distributed with the same mean as the popualtion mean. If the popolation variance is s2 then the sample mean has a variance is s2/n. As n increases, the distribution of the sample...
When alpha is 2 or less than 2 the variance of the inverse gamma doesn't exist. That is why when the variance is defined for the inverse gamma it always says "for α > 2".
It is also the case that...
you have to add all the numbers in the problem together and then when you get that answer you divide that answer by the number of numbers in the problem.
-Totallytorie.
Another word for the mean is...
if its in math; you'll add all the following #s and divide it by the amount of number there is.. for example: 2,3,1,9,1
2+3+1+9+1=16...... now divide it by 5 since theres 5 #s which equals 3.2
Yeah...
