I am getting an error when I put in these two codes. I am using Stata 12.
I have recoded CHILDREN already as a dummy variable called CHILDRENDUMMY and the variable is located in the list of variables. I am trying to run two margins commands, but I am getting the error message
vsquish CHILDRENDUMMY not found in list of covariates
Can someone please help me?
First Code
margins, dydx (DISAGMT) at (CHILDRENDUMMY= (0 1)) vsquish
Second Code
margins, at dydx (DISAGMT= (0) CHILDRENDUMMY= (0 1)) vsquish
See http://www.stata.com/help.cgi?margins for current syntax.
You should see that you have confused margins on what you think is a covariate. For example, vsquish is an option, not a covariate. How did that happen?
The second syntax is not what you want, as at() needs an argument. That's like saying "meet me at" without time or place.
You don't say what you want to do, but my guess is more like
margins, dydx(DISAGMT) at(CHILDRENDUMMY=(0 1)) vsquish
Note that option names and their arguments should not be separated by spaces: the form is foobar(frog) not foobar (frog).

This might be similar to this question (pre_limit_mult in synth_runner package stata does not work), However, I ask this because I could not find any useful tips from the link.
I am trying to use the pre_limit_mult(real) option to limit the placebo effects in the pool for inference. The ultimate purpose is to test the validity of estimation of the economic impact of the coup in Gambia in 1994.
However, even though I follow the practice as the guidebook explains, the command does not work and present the message like the following.

Does anyone know how to fix it?
I got some trouble with nomenclature in Elsevier template. I followed this instruction proposed by delrocco.
and now when I wrote the \nomenclature command I got nothing (the box is empty)(please see the attached file). I do not know I must use tabular environment in the middle of the table* environment or use \nomenclature command. When I use tabular environment, I have columns that with different size (the fourth column go out of the box)(the proposed instruction needs making some change in template). I do not know it is the best solution or not. Also when I use the other solution with \mbox commant i received the error relates to the not proper for two column. I m confused.
I really appreciate any help

I know how to do this in R: e.g. pchisq(18.98, df=2, lower.tail=FALSE)
However, I've no idea about how to write Stata code to solve this problem.
In case you're interested in more general post-estimation tests check out: help test.
Otherwise is seems like chi2(2,18.98) or chi2tail(2,18.98) are what you're after (depending on what lower.tail=FALSE means.
Note that in Stata you'll probably want to put this into a "local" in order to do other things with the output.
For example if you say the following to Stata:
local pchi2 = chi2(2,18.98)
display "chi2: `pchi2'"
Stata should reply:
chi2: .9999243958967154
See for more detail and links to the Stata manual section on statistical functions:
help chi2
help chi2tail
I've set up a Google Sheets workbook that synthesizes data from a few different sources via manual input, IMPORTHTML and IMPORTRANGE. Once the data is populated, I'm using INDEX MATCH to filter and compare the information and to RANK each data set.
Since I have multiple data inputs, I'm running into a persistent issue of names not being written exactly the same between sources, even though they're the same person. First names are the primary culprit (i.e. Mary Lou vs Marylou vs Mary-Lou vs Mary Louise) but some last names with special symbols (umlauts, accents, tildes) are also causing errors. When Sheets can't recognize a match, the INDEX MATCH and RANK functions both break down.
I'm wondering how to better unify the data automatically so my Sheet understands that each occurrence is actually the same person (or "value").
Since you can't edit the results of an IMPORTHTML directly, I've set up "helper columns" and used functions like TRIM and SPLIT to try and fix instances as I go, but it seems like there must be a simpler path.
It feels like IFS could work but I can't figure how to integrate it. Also thinking this may require a script, which I'm just beginning to study.
Here's a simplified example of what I'm trying to achieve and the corresponding errors: Sample Spreadsheet
The first tab is attempting to pull and RANK data from tabs 2 and 3. Sample formulas from the Summary tab, row 3 (Amelia Rose):
Cell B3: =INDEX('Q1 Sales'!B:B, MATCH(A3,'Q1 Sales'!A:A,0))
Cell C3: =RANK(B3,$B$2:B,1)
Cell D3: =INDEX('Q2 Sales'!B:B, MATCH(A3,'Q2 Sales'!A:A,0))
Cell E3: =RANK(D3,$D$2:D,1)
I'd be grateful for any insight on how to best index 'Q2Sales'!B3 as the correct value for 'Summary'!D3. Thanks in advance - the thoughtful answers on Stack Overflow have gotten me this far!
to counter every possible scenario do it like this:
=ARRAYFORMULA(IFERROR(VLOOKUP(LOWER(REGEXREPLACE(A2:A, "-|\s", )),
{REGEXEXTRACT(LOWER(REGEXREPLACE('Q2 Sales'!A2:A, "-|\s", )),
TEXTJOIN("|", 1, LOWER(REGEXREPLACE(A2:A, "-|\s", )))), 'Q2 Sales'!B2:B}, 2, 0)))
I'm trying to save output from several hundred eststo's storing results of bivariate probability models into one excel file using esttab. It works for xtlogit(both ,re and ,pa), xtprobit (both ,re and ,pa) and for the linear probability model xtreg (both standard and ,fe. However, when I use xtreg y x i.year, fe I get the error message too many base levels specified. Google doesn't help me much.
I've been trying for an hour to create a reproducible example but the stata datasets all work fine. It does not seem to be due to the number of years or the fact that different specifications have data for different years. Still, the normal xtreg, fe' works, the problem only appears with time dummies. The weirdest thing is that it works for all subsets of my variables but not for the whole list (again just the time fixed effects specifications).
Does anyone have an idea how to proceed? Using drop(*.year) works whenever the problem does not arise (so in specifications where it works, I get outputs without the year dummies) but does not prevent the too many base levels specified error; ,nobaselevels has no apparent effect as well. Is there a way to remove the time fixed effects from eststo before I pass those on to esttab? Any workaround would be appreciated as well.
The problem you might be facing is that of Stata creating different base levels for the factor variable year, in different regressions.
Try fixing the factor variable base level beforehand with fvset:
fvset base <some_number> year
Check help fvset and the manual entry for details. Also, read the source given below, which contains more information.
