Probability density function represents

WebbA density curve describes the overall pattern of a distribution. The area under the curve and above any range of values is the proportion of all observations that fall in that range. De nition 3.6 from the book: The function f(x) is a probability density function for the continuous random variable X, de ned over the set of real numbers R, if 1 ... WebbThe curve is called the probability density function (abbreviated as pdf). We use the symbol f(x) to represent the curve. f(x) is the function that corresponds to the graph; we …
