[parent] Viewing Correction to 'density function'
density function of continuous RV by dw

Correction text:
 "let p_x the probability of X taking a particular value x and then make f(x) equal to p_x (and 0 if is not in the sample space)."

I would suggest leave this part out. It is incorrect. For a continuous random variable "the probability of X taking a particular value x" is always zero. The _density_ function may not be zero at x, but the _probablity_ that X=x is zero.

you're right by drini on 2005-02-20 13:59:47
yeah you're right, as it stantds, the entry is incorrect. But instead of just removing that sentence, perhaps it'd be better to replace it with a better option

can you suggest a better way to define it?
