Proceedings of the 34th international workshop on statistical modelling volume II

For 34 years now, the International Workshop on Statistical Modelling (IWSM) has been a reference for promoting and encouraging statistical modelling in its widest sense. IWSM is now one of the most prestigious world conferences in Statistical Modelling, regularly attracting academic, professional statisticians and data analysts from all parts of the world. In 2019 the International Workshop on Statistical Modelling took place in Portugal. According to the workshop tradition, in this edition student participation has been strongly encouraged not only to attend the workshop but also to present their work. Students attending the conference had the possibility to compete for three awards: best student paper, best student oral presentation and best student poster. In addition to this, two student travel grants have been provided by the Statistical Modelling Society (SMS). We hope that the Short Course "Statistical modelling with missing data: challenges and practical solutions" given by James Carpenter (London School of Hygiene & Tropical Medicine) was of their interest. Following the latest tradition of IWSM, two proceeding volumes with manuscripts of presented papers (both oral and poster presentations) are published and distributed at the conference. Part I of proceedings which will be printed will contain all papers being orally presented during IWSM. Part II of proceedings will contain papers corresponding to poster presentations and will be available online
