WebFeb 21, 2024 · Recorded with http://screencast-o-matic.com WebThe PDF is the density of probability rather than the probability mass. The concept is very similar to mass density in physics: its unit is probability per unit length. To get a feeling for PDF, consider a continuous random variable X and define the function f X ( x) as follows (wherever the limit exists):

Web1 f obviously is not a PDF, because it takes on negative values when x is negative. It is probably intended that f ( x) = 0 when x ≤ 0, but--especially for solving problems that involve computing with PDFs--it is crucial that you specify this explicitly. – whuber ♦ Mar 20, 2016 at 23:22 What is the definition of median?
