# Does the below Plot refer to a Valid PDF?

I have tried to creat a valid PDF according to some special function I have got the below Plot , I got it for n=6 Integrand Range[n/n], Now My question here Is : Is that below Plot refer to a valid PDF or should I improve it to be closer so much to 1 ?

• Please don't try to guess whether something is a valid density function by looking at plots! Instead, check whether the function used to generate the plot satisfies the criteria required for it to be a PDF. In your case, I am guessing that your function is absolutely continuous and integrable, in which case the criteria would be $f(x) \geq 0$ everywhere and $\int_{-\infty}^{\infty}f(x)\text{d}x = 1$; see statlect.com/fundamentals-of-probability/… for more. – jbowman Dec 5 '19 at 20:08
