The name of this probability density function

Click For Summary

Discussion Overview

The discussion revolves around identifying the name of a specific probability density function defined as f(y) = aeby - cy². Participants explore its characteristics and potential classifications, including its support and relation to known distributions.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant inquires about the name of the probability density function f(y) = aeby - cy².
  • Another participant suggests that it resembles the normal distribution and recommends completing the square in the exponent.
  • A different participant notes that the function has support in the range y ∈ (0, ∞), which may affect its classification.
  • One participant proposes that this characteristic could indicate it is a truncated normal distribution.
  • Another participant expresses agreement with the idea of it being a truncated normal distribution.

Areas of Agreement / Disagreement

Participants express differing views on the classification of the probability density function, with no consensus reached on its exact name or nature.

TL;DR
Looking for the name of some probability density function.
Does anyone knows the name of the probability density function

f(y) =aeby-cy2

Isn't that just the normal distibution? Complete the square in the exponent.

Could be, but this function has support $$y \in (0, \infty)$$.
 
I think that just makes it a truncated normal.
 
I thought so too.
