N（名词） a function representing the relative distribution of frequency of a continuous random variable from which parameters such as its mean and variance can be derived and having the property that its integral from a to b is the probability that the variable lies in this interval. Its graph is the limiting case of a histogram as the amount of data increases and the class intervals decrease in size 概率密度函数 (Also called density function) [statistics] → compare cumulative distribution function, frequency distribution
