The Penis Equation

The Penis Equation

Does anyone know of a good formula for finding cumulative percentage of penis size? I’m looking for the equation for the average penis length bell curve. If all else fails and no one wants to answer this I’ll just use our pre-PE polls and come up with an equation. I was hesitant to use our poll as it might be slightly less than average.

Would love to help, But I suck at Math.


:dance:

the equation for a basic bell curve is this:

y = 1/sqrt(2*pi)*exp(-(x^2)/2)

You can tweak the variables to adjust the dimensions for the penis size if you know the average size and the lower quartile/upper quartile.

To find the cumulative frequency you need to calculate the area underneath the curve, i.e. its integral. However for this equation there is no finite equation for the integral, so you are better off getting a computer to approximate it by brute force (the trapezium rule).

p-pal put up some great data on this a while back based on the database. It might save you time if you look up that thread and use the data from that for your calculations.

Thanks SS4 I’ll check that out.

Olaf, I understand the math behind all of it, I just need help finding the true average size and the lower quartile/upper quartiles. I sadly made a program on my graphing calculator that predicted my gains and would then correspond them to an integration of the bell curve for volume. But it’s not very accurate, I took a lot of guesswork on the exact numbers while making it. If I get to something worth while, I’ll post it.

P-pal’s information is very good, but not quite what I’m looking for. I’ll do some work on this later on.

Joe, what is your routine? You made some good gains.

Damn, Math is my favorite subject.. Then I read that equation. Don’t bother trying to explain it to me, Just saying whoever came up with that.. Dang, good job.

In all honesty, I’m still sticking to the newbie routine. I just add a little more time on occasion. Right now I’m up to 10-15 minutes of stretching and 10-15 minutes on jelqing 4-5 days a week. I’m not very precise as you can tell.
