Identification of a probability density function

Click For Summary
SUMMARY

The discussed probability density function is defined as $$f(x) = \frac{2^{\frac{1}{2}~\frac{a_{0}-c_{0}}{a_{0}}}~a_{1}^{(-\frac{1}{2}~\frac{a_{0}+c_{0}}{a_{0}})}~c_{1}^{(\frac{1}{2}~\frac{a_{0}+c_{0}}{a_{0}})}~x^{\frac{c_{0}}{a_{0}}}~e^{-\frac{1}{2}~\frac{c_{1}~x^{2}}{a_{1}}}}{\Gamma(\frac{1}{2}~\frac{a_{0}+c_{0}}{a_{0}})}$$ for $$x \in (0, \infty)$$. This function can be identified as a gamma distribution after the substitution $$u = \frac{x^2}{2}$$, where the parameters are $$\alpha = \frac{c_0/a_0 + 1}{2}$$ and $$\beta = \frac{a_1}{c_1}$$. The discussion confirms that this transformation leads to a recognized distribution, providing clarity on its classification.

Identification of a probability density function.
I have the following probability density function:

$$f(x) = \frac{2^{\frac{1}{2}~\frac{a_{0}-c_{0}}{a_{0}}}~a_{1}^{(-\frac{1}{2}~\frac{a_{0}+c_{0}}{a_{0}})}~c_{1}^{(\frac{1}{2}~\frac{a_{0}+c_{0}}{a_{0}})}~x^{\frac{c_{0}}{a_{0}}}~e^{-\frac{1}{2}~\frac{c_{1}~x^{2}}{a_{1}}}}{\Gamma(\frac{1}{2}~\frac{a_{0}+c_{0}}{a_{0}})}$$

Is this a known probability density function?

I don't know what you call that distribution, but if you make the substitution u = x2/2 then u has a gamma distribution with α = (c0/a0+1)/2 and β = a1/c1.
