Replication of Research

Not sure how many pages I need but I need the writer to replicate a research study. Attached are my STATA and Regression. Correct anything that looks wrong and then replicate this research paper. Do not copy. Add your own spin to the research! Attached is the paper you are replicating also!
Can you tell the writer a replication of a study is repeating a study’s procedure and observing if the prior findings repeat in similar conditions. A study is replicated when the results of original study are as closely related to the newly collected data. Just some info to help them out.
