P-value from table1mc table

[Mary Burda]

Hello,

I made a table using the table1mc command and have three columns, a total, respondents who have undergone an intervention, and those who have not. Table1mc displays a p-value for those 2 different groups.
However, I cannot use survey weights with the table 1 command, so I would like to re-do the table manually (unless someone knows how say would work with table1mc).
The problem I have is that I dont know how to calculate the p value for the difference between intervention/non intervention (it is a variable with either 0 = no for the ones who have not been part of the program or 1 = yes for the ones who have) using the svy command.
I feel like this should be pretty simple to do but I am new to Stata and couldnt figure this out so would appreciate any help!

What command are you using with the -svy- prefix? Do you have stratification?

[Rich Goldstein]

the -table1_mc- command (note spelling) from SSC (as you are asked to explain - see the FAQ), accepts pweights and that is how you should use this command with survey data; see

h table1_mc

h table1_mc

My help file says that only fweights are allowed, not pweights (which I use)

Is it correct that the p value from the output of table1_mc is from Pearson's chi square? If so, is there a way to use that with the svy: prefix? Whenever I try that, it tells me that chi2 is not allowed with svy. Or could I instead do a t-test? Basically, I want to test for statistical significance between the two values my intervention variable has

is this the version of table1_mc you have?

. which table1_mc.ado

the basis of the p-value is the test you requested, which in some cases is Pearson's chi-squared - but you did not show your command so I can't answer re: what you received; what test you should be using depends on what your data are - and you haven't told us that

yes, that is the version I have.

my table1_mc code is:
table1_mc, by (interventionvar) vars(list of all the other variables) total(before)
and when I try to use weights, it tells me "option pweight not allowed"

interventionvar is a variable that has 2 values, 0 for no, 1 for yes

I just found out though that using the tab command with svy automatically gives values for chi2, so that might solve my problem.
