WebFirst, finding the cumulative distribution function: F Y ( y) = P ( Y ≤ y) Then, differentiating the cumulative distribution function F ( y) to get the probability density function f ( y). That is: f Y ( y) = F Y ′ ( y) Now that we've officially stated the distribution function technique, let's take a look at a few more examples. WebProbability Density Function The general formula for the probability density function of the normal distribution is \( f(x) = \frac{e^{-(x - \mu)^{2}/(2\sigma^{2}) }} {\sigma\sqrt{2\pi}} \) where μ is the location parameter and σ is the scale parameter.The case where μ = 0 and σ = 1 is called the standard normal distribution.The equation for the standard normal …
Web14.6 - Uniform Distributions. Uniform Distribution. A continuous random variable X has a uniform distribution, denoted U ( a, b), if its probability density function is: f ( x) = 1 b − a. for two constants a and b, such that a < x < b. A graph of the p.d.f. looks like this: f (x) 1 b-a X a b. Note that the length of the base of the rectangle ...
