I recently ran across a new probability distribution called the “Scaled Beta2” or “SBeta2” for short in [1]. For positive argument x and for positive parameters p, q, and b, its density is. This is a heavy-tailed distribution. For large x, the probability density is O ( x–q-1 ), the same as a Student- t ...

WebDetails. The CDF function for the gamma distribution returns the probability that an observation from a gamma distribution, with shape parameter a and scale parameter λ, is less than or equal to x . The equation follows: C D F ( G A M M A , x , a , λ ) = { 0 x < 0 1 λ a Γ ( a ) ∫ 0 x v a - 1 e - v λ d v x ≥ 0. WebThe beta distribution is used to model continuous random variables whose range is between 0 and 1. For example, in Bayesian analyses, the beta distribution is often used as a prior …

Parameter Estimation The method of moments estimators of the 2-parameter gamma distribution are \( \hat{\gamma} = (\frac{\bar{x}} {s})^{2} \) \( \hat{\beta} = \frac{s^{2}} … WebHence you have to scale the y-axis by 1/2. For instance, if you've got a rectangle with x = 6 and y = 4, the area will be x*y = 6*4 = 24. If you multiply your x by 2 and want to keep your area constant, then x*y = 12*y = 24 => y = 24/12 = 2. Scaling the x by 2 = scaling the y by 1/2.
