WebFeb 11, 2024 · You're actually going to have a problem with this approach: the original CDF isn't continuous, which means that your random variable isn't continuous and won't have a genuine density function. WebA PDF is simply the derivative of a CDF. Thus a PDF is also a function of a random variable, x, and its magnitude will be some indication of the relative likelihood of measuring a particular value. As it is the slope of a CDF, a PDF must always be positive; there are no negative odds for any event.
WebThis is the kind of problem that gives integration a bad name among students. Draw a graph of the density function. It looks like an isoceles right triangle with hypotenuse $2$ and apex at $(0,1)$ and very obviously has area $1$ (useful as a check on one's work.)

In probability theory one considers functions too: De nition: A non-negative piece-wise continuous function f(x) which has the property that R 1 1 f(x) dx= 1 is called a probability density function. For every interval A= [a;b], the number P[A] = Z b a f(x) dx is the probability of the event. 23.2.
