Problem running RDS command for RDS analysis

[Thea Jensen]

Dear Stata List members,

I am trying to run a respondent driven analysis (RDS) in STATA. I use the user written program by Matthias Schonlau but am experiencing problems - it does not run unless I reduce my dataset. Instead, it freezes after "Number of categories of (gender): X Number of seeds= X".

My dataset includes 3,575 observations and respondents can recruit as many new respondents as they are able to - in this case up to 156. I am wondering if it is the number of recruitments/coupons (ncoupon=156) that is causing the problem. However, I was able to run the analysis in R without complaints about the number of referrals (unfortunately, I have to run it in both STATA and R).

Has anyone experienced similar challenges or has any idea to how I may solve this?

Thank you in advance for sharing your experiences and thoughts on the issue.

Sincerely,
Thea

The code I use is:
rds_network gender, id(mobile) coupon(number) degree(networksize) ncoupon(156)

Welcome to Statalist, Thea.

I note that the output of help rds gives an email address for Matthias Schonlau, the program's author. If nobody here is able to contribute any insight, perhaps he would be able to address this question in response to email.

Dear William,

Thank you so much for responding to my question - I will try to reach out directly to Matthias Schonlau.

Sincerely,
Thea
