Earlier last week, I submitted my PhD thesis after:
4 years,
40,000 words,
4 scientific publications,
6 international conferences
Many thanks to everyone who was part of this journey!

Just for the record, there are currently 7 million Bulgarians living in the country and 6 million living outside. 6 million! I am one of them. But seeing all these people thirsty for change and their anger caused by the injustice gives me hope.

Hello, thanks for the suggestions ! We are interested in both - models that are used in practice AND recommended in the guidelines! ☺️

P.S
The review is exploring how CPMs handle missing data during model development, validation and implementation. 📈
We have not been able to figure out how to systematically search for such models. Any thoughts how to do this are also welcomed!
