Discussion Overview

The discussion revolves around the possibility of adjusting the beta distribution to span from -A to A, rather than the standard range of 0 to 1. Participants explore the characteristics of U-shaped distributions and seek alternative probability density functions (PDFs) that exhibit similar properties.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant suggests that the beta distribution can be adjusted to fit a U-shaped distribution centered at 0, spanning from -A to A, but seeks confirmation and additional options.
  • Another participant notes that the beta distribution can produce a U shape when the parameters alpha and beta are both less than 1.
  • A different participant proposes that the probability density function of a sine wave also represents a U-shaped distribution and questions the existence of other distributions that could fit this requirement.
  • One participant requests more details to provide further assistance, indicating that additional information is necessary to explore the problem effectively.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the adjustment of the beta distribution or the identification of alternative distributions. Multiple competing views and suggestions remain present in the discussion.

Contextual Notes

Some limitations include the lack of specific details about the desired properties of the distribution and the potential need for further clarification on the mathematical adjustments proposed.

I have is a distribution that is U-shaped, centered at 0, spanning from -A to A, and I want a means to model this, a beta distribution is the closest thing I have found to kinda do this

can the beta distribution be adjusted to range from -A to A as opposed to 0 to 1? any other suggestions as to distributions to use?

You're going to need to post more details.
 
The probability density function of a sin wave is a U shaped distribution, let's say from -A to A, where A is the amplitude of the sin wave. The beta distribution is the closest thing to a U shaped distribution I have found when the parameters alpha and beta are less than 1. I have found a way to adjust the range of the beta distribution

however, what I want to know are there any other PDF distributions that generate a U shaped plot. Beta is the only one I have found so far, wasnt sure if there was an obscure one out there under my nose
 
Essentially, X~Uniform(domain) so you want to find the distribution of f(X). I can't help you anymore unless you give more information.
