Can distribution functions be negative
WebCan distribution function negative? But distribution function is an increasing function on R thus its derivative is always positive. Assume that probability density of X is -ve in the interval (a, b). … But by definition, probability can never be negative. Thus, density can never be negative. WebAny function f (x) is potentially a P.D.F. if its satisfies two conditions: f(x) is non-negative and its integral is equal to one. Satisfying these conditions, the PDF can be greater than 1.

WebAug 19, 2015 · A wavefunction with negative sign works just like any other wave with negative sign. For example, water waves with negative height cancel out with waves of positive height. You can also make a 'negative' wave on a string by pulling the end down and back up, which will cancel with a positive wave.
