QUESTION
following are my files for html, .ts and json . As json data was very extensive therefore i have just added a few states and their cities. my 1st dropdown is showing all states.

Answered 2021-Apr-27 at 16:44You can do it with the $event
parameter.
Make sure to compare your values safely.
If your value is not in the right type or has spaces or unwanted chars, this c.state == val
might not work.
You can use the trim
function to compare your value safely:
c.state.trim() == val.trim()

We had a very similar crash and solved it by using a unique id for the navigation graph.
QUESTION
So I am really fond of the stargazer package for displaying the statistics for regression models. I've been using R and Stata together to complete some problems in a textbook. One issue that I have found is that the confidence interval printed by the stargazer package does not correspond to the confidence interval by stata. I determined that the CI in stata is the correct one after doing it by hand.
Because the issue might may possibly lie in how I am handling the data, I offer it here as an optional choice. My primary concern is to determine why the CI's do not respond. From a previous post, here is one possible way of finding the data I am using;
...ANSWER
Answered 2017-Sep-05 at 14:53The simple answer is that stata and confint
calculate confidence intervals using the t-distribution, while stargazer
's internal method uses the normal distribution. The result is that the former two are more conservative in their estimates and thus have wider CI compared to stargazer
. (Well, I'm assuming with stata here, but since it gives the same results as confint
I feel it is a safe assumption).
Looking deep into the source code for stargazer
(line 688ff) we can find how CIs are calculated:
