Interpretation of output from the 'churdle' command

[Peter Sommer]

Hello,

I am currently planning a study and started thinking about the proper econometric approach to my data. While doing that I have come across the churdle command.
From what I can see in the Stata helpo file, this command provides an output table that is subdivided into the main output as well as two selection outputs (selection_ll, selection_ul), with the latter representing the lower bound and upper bound values that one has to defined based on the data structure.

I have googled for quite a while and cannot make sense of the interpretation of the output table. Can anyone give me a generic answer explaining how to properly interpret any given value in the main output, selection_ll, and selection_ul output? What is the meaning behind the values in either sub-table?

I don't have any specific data output to show since I have not yet obtained my data yet. But I would simply like to understand the meaning behind this command and the standard Stata manual is really no help.

Sincerely!

Peter:
why not reading the -churdle- entry in Stata .pdf manual and get yourself familiar with that stuff by challenging yourself with reprducing the reported examples?

[Peter Sommer]

But - as stated in my initial post - I tried to read it. I simply have issues understanding what those terms mean and asked for help.
If someone could explain this in plain, simple language on the basis of some fictitious data - I would greatly appreciate it.
I will still work with the data myself, I'm merely asking for an explainer.

There is a Youtube video explaining the churdle example in the Stata help pdf at

Peter:
in your first post you did not seem to mention Stata .pdf manual: hence my advice (for what it worths).
I still benefit from replicating Stata example myself (and reading related references; by the way, you may want to take a look at: https://journals.sagepub.com/doi/pdf...867X1301300406) but, as usual, a size doesn't fit all.

I refered to this as the 'Stata help file' in my initial post.
In any case, for now I was simply interested in a easy-to-understand summary of what those outputs mean without having to dive into the hardcore econometrics. Thanks Red Owl for the link.
