F1(x)及F2(y)称为F(x,y)的边际分布函数(Marginal Distribution Function)。 [例]若F(x,y)是连续型分布函数,有密度函数f(x,y),那么 因此F1(x)是连续型分布函数,其密度函数为 同理F2(x)是连续型分布函数,其密度函数为 f1(x)及f2(y)的边际分布密度函数。 [二元正态分布]函数 这里a,b, ,r为常数...
Distribution function教程.pdf,Distribution function: The distribution or probability density functions describe the probability with which one can expect particles to occupy the available energy levels in a given system. A particles distribution function
is theprobability density functionof . Example The simplest example is probably the cdf of theuniform distribution. The probability density function of a random variable having uniform distribution on the interval is where is an indicator function that takes value 1 on the interval and value 0 ever...
