I am learning causal inference and I want to use a very popular dataset(the dataset is created in 1999). I find the webpage of it and many papars citing it. However, I never ever to find the download link. I wish someone could help me about it. It is a dataset belongs to
The website about
Prevention of Suicide in Primary Care Elderly: Collaborative Trial (PROSPECT). The funniest thing is that the website allows me to download the query results instead of dataset of study.
If you guys can give me some advice about it or provide me several causal inference dataset(experiment data and observational data), I will be very grateful!
