Webb1 aug. 2024 · The probability density may be greater than 1 (e.g., a normal distribution with σ = 1 / 100 has a probability density of almost 40 at 0), or it may be very small everywhere (one with σ = 100 has its greatest density at 0 of ∼ 0.004 ). Instead the curve tells you something about the probability of different numbers relative to each other. Webb16 okt. 2024 · If we have a probability distribution function F X ( x) then its probability density function limits − ∞ to + ∞ f X ( x) d x; and it is for continuous variables.
