Cox proportional analysis

[Laura Fernandez]

Hi,
I am running a cox proportional analysis for stock data to see if stocks with higher levels of CSR are able to reach their value to pre-pandemic levels faster. As I am trying to run this I have come across a problem. The stocks that do not reach their pre-pandemic levels by end of the study period, are characterised with the failure value of 1, however, the time variable will always equal the same number of days for all the stocks with failure value of 1, for instance 365 days for my study period. Therefore, the coefficient results are a bit odd and also the p-value is equal to 1 for all variables. Would greatly appreciate any help.

Thanks in advance

welcome to this forum.
Unofrtunately, this kind of questions run the risk of being left unreplied, because potentially interested listers know neither what you typed and what Stata gave you back, nor can rely on an example/excerpt of your dataset.
Both this topics are covered in the FAQ, that first time posters (as we all were, when we decided to participate in this forum) are kindly requested to read and act on. Thanks.
