Normpdf greater than 1 symbol

The probability density function is nonnegative everywhere, and its integral over the entire space is equal to one. The area under the graph is the area of a rectangle. More generally, if the density has a large value over a small region, then the probability is comparable to the value times the size of the region. I say "comparable to" rather than "equal to" because the value my not be the same at all points in the region.

Your Answer

Density means probability per unit value of the random variable. If we know a PDF function e. To find the probability that the output of a random event is within some range, you integrate the PDF over this range.

I would like to point out an extreme example. It will be the same. So the bottom line here.

Consider a probability density function of some continuous distribution. Why it is called density function?? Unlikely the probability mass function of a discrete distribution p. Conventionally probability of a point is considered as '0' for continuous distribution.


Then comes the question what actually does p. Now the physical interpretation of density is ratio of mass and volume of a substance. Here probability density function is similarly the mass which is similar to the frequency and the volume which is similar to the field of experiment ratio.

This only holds for discrete random variables. Home Questions Tags Users Unanswered. How can a probability density be greater than one and integrate to one Ask Question.

Is it 1? If you take a fixed mass of liquid and compress certain parts of it, you can make the local density as high as you like without changing the total mass.
