No thesis would be accomplished without the following smaller and bigger personae. I am indebted to:  My international family: the Erasmus Mundus Program students who not only substituted my family but also perfectly complemented it, notably/especially, notably  Alice for sending me nicely strong Karma coffee from the Laos mountains and lemongrass tea from Thailand to wind down from the coffee effect, Esfandiar, Yan, my Kabutar Mina for millions "miss you", "miss you" words!, my awe-inspiring friend Tara, and my Chinese little sister Guodi. This one’s for you. You probably know why. My second international family for sharing the floor in the American Fondation:  my favorite dancing Rida for her never-failing optimism, my American Polish brother Mark Zaborowski, multitalented Baidy, and to Tierra for her writing talent who helped me struggle scrape  through my very first scientific paper. Ana, the real fighter and the Taekwondo Master for "<3s" and accepting me as I am;

Meno, Vadim, godfather Marouene, Adams - the tektonic specialist and the best uncle, Hamza number one and Hamza number two, the rockets builder Heric, and finally the most talented and probably the youngest Senior Researcher from the Statistics Finland. Hi Henri.  Friends from Ifsttar and the Laboratory DEST: DEST Laboratory:  Benoit for showing me how cool French people can be;  "Super irritating" "Irritating"  Davidfor teaching me how to have a bigger distance to myself,  who kept on reminding me not to take myself too seriously; Katia, Christine, and Hoai-Thu, the Ifsttar super mothers!;  and the most original and the best coiffée X from the Ifsttar cafeteria for providing the strong enough coffee.  Prof. Michel Bierlaire who let me join his team at the École Polytechnique Fédérale de Lausanne for a couple of months during my thesis and who gave me the chance to answer correctly maybe two out of his hundreds super challenging questions; and all the members of his team: always in trouble Yousef, Shadi, Marija, the genius Iliya, eating porridge at 4 P.M. Flurin, Antonin, running fast Tomas, Evantia, Ana, strong Riccardo, Anna,  and Stefan. My heroes:  Prof. Anselin who I never met in my life but who is responsible for my love to spatial analysis and whose work in many ways motivated this project;  My idol, Prof. LeSage who I had a tremendous honor to meet and to  talk to about my research, whose comments helped clarify my own thinking, and who almost convinced me that Bayesian analysis is the remedy to all the World's problems; Prof. Krzysztof Malaga, a definition of hard work and a great example tothe  students. Nicolas, with whom looking for new ideas and writing articles was an unspeakable joy of creation, for stayingsuper  attentive and excited after not closing an eye during a couple of nights. Not an easy task to be a multi-task young father-researcher. Matthieu the best supervisor you could imagine to work with, to whom I have a huge respect for not only being a great professional mentor, but especially a great human.  Finally, I am most deeply thankful to the closest ones:  My father, the best advice-giver and the fantastic professor, who install installed  within me a love of science, who encouraged me to change my study field from finance and banking to econometrics. Thank you for being stubborn enough at that moment of my life!; My father (the same one) to whom I promised that I will never ever go for a PhD. He waited for a moment and said... "Oh yes, darling, you will";  My mom for her never-ever-ending support (literally), for these thousand Whatsapp, Facebook, gmail, phone... messages per day. Dziekuje!;  My grandma, the most energetic grandmother on Earth, I guess;

Love you guys.  After these couple of words worthy (or not) of your attention before the story even begins... 3,5 year that this thesis was in the making. Here're four chapters. Nearly everything I intended is in it, and still the thesis is not full. I cried, I hurt, I tried, I failed, and I fail failed  again, and I learnt. Good and bad ideas are in it, it  along with only a little bit of despondency and enormous pleasure of discovering. Here're four chapters through which I tried to briefly and gracefully communicate four things. Each chapter tells one story. All the stories create an image which definitely I  could be further being painted. So let definitely keep on painting further. But let's close it for now, let's draw the curtains and put  the light on. Here my  story begins...
