WebbAt each t, fX(t) is the mass per unit length in the probability distribution. The density function has three characteristic properties: (f1) fX ≥ 0 (f2) ∫RfX = 1 (f3) FX(t) = ∫t − ∞fX. … Webb2 apr. 2024 · The probability density function (pdf) is used to describe probabilities for continuous random variables. The area under the density curve between two points corresponds to the probability that the variable falls between those two values. In other words, the area under the density curve between points a and b is equal to P(a < x < b).
