exp_mod_normal parameter lambda is inverse scale, not shape

[andrewdolman]

Summary:

In the current Stan Function Reference manual Version 2.28. For the Exponentially modified normal distribution, the parameter lambda is described as being the shape, I think it is actually the inverse scale, or rate parameter.

Description:

Describe the issue as clearly as possible.

Additional Information:

I tried to follow the contributing guidelines but could not find a "currently open next docs issue"

Current Version:

v2.18.0

@andrewdolman: thanks! We'll fix it.

We used to just have one docs issue and I'd personally just clean everything up before a release. Now it's way too big for that, so we just create issues for each issue.

If you let me know where you found that guideline, I can update it. I can't find it with Google search over our docs.

If you create a new issue there is a link to contributing guidelines which points to this: https://github.com/stan-dev/docs/blob/830169f1f63d18b82eda8befaf22b53bde975fe0/.github/CONTRIBUTING.md

Huh, I hadn't noticed that little auto-generated link on the side of the issue bar. We should probably just delete that file

[bob-carpenter]

Is this a pop-up when someone opens an issue? If so, we definitely want to just get rid of this advice and instead maybe just thank them for reporting an issue.

It shows up in the righthand column as the "Contributing" link under "Helpful resources"
