WebAt 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. A random variable (or distribution) which has a density is called absolutely continuous. This term comes from measure theory. Web24 sep. 2011 · This is because density is a function of resolution and physical size, and manufacturers tend to pick a screen size that fits the display resolution.
