   Thank you. One of my personal goals with regard to this analysis was to learn Python on-the-go (I feel more comfortable in R) so I will definitely check pymc3.

   I only reported plots I found interesting/saw some resemblance between HN and SO and in case of Rust probably none of those was he case. However, it must be said that I didn't have any quantitative criterion for this and this deci

   Hey, thank you for informative comments. I would gladly read more about hierarchical Bayesian regression. Would you recommend any sources from which I could learn more? (I am fully aware that I can google it but in my opinion it's usua

   Hey, thanks for the comment. I am fully aware of that and did not stated otherwise in the analysis. I only established that there seems to be some kind of relationship but it is not possible to determine causality.

   Thanks for pointing this out, I didn't think about this. Nevertheless, I assume that in an ideal situations when documentations for two programming languages have the same quality then the number of questions for the programming langua

   Thanks! I wasn't aware that such a function exists.

   Hey, I was thinking about writing something like that in the analysis. I finally decided not to do this because languages develop over time. I'm not a user of Java/HTML/Pascal/PHP but I use SQL quite frequently and in my

   > Yeah, I'm sure the causal arrow goes both ways. Even not fully realizing this (see my replay to @tofflos) I did not exclude such a possibility and that's why I performed the Granger causality test for both hypotheses (SO in

   I was thinking rather otherwise, that is that people who use certain technology (technologies) would check posts about them on HN. Your point of view did not come to my mind so thanks for pointing this out.

    Hey, thanks for the comment. I am aware that "correlation is not causation" and did not stated otherwise. The correlations would not answer the original question about the causation and it seems like this analysis cannot cope with

    Fair point , thank you for the feedback. As I wrote, I did not detect causation (except for a couple of examples in which the null hypothesis of Granger causality test was rejected). The aim of the analysis was to find relationships between
