Simone and Malcolm Collins present relationship theory and advice in a manner that is at once empathetic and devoid of sentimentality. As strange as this sounds, the combination works. In fact, it's a lot of fun to see relationships get dissected and rehashed from a more economic and biological perspective (rather than an emotional one). Research: We review and conduct research with the goal of helping people engage in self reflection and seriously consider new ideas so that they can independently determine—for themselves— the best possible ideas and solutions to adopt. So there, if you are interested in romantic relationships, if you think you are missing those in your life, read this book. It will give you a lot of knowledge. The trade-off though is that you will have to give up your fantasies, and do not take that lightly, that is very hard to do. If you can do that, though, this book will give you tools, as blunt as they may be (pun intended) that can be invaluable on your way forward in this world. And god only knows, in this world, we need all the tools we can get.

The thing is, if your model exhibits perfect multicollinearity then there are multiple (in fact infinite) solutions to the problem of minimizing the least square sum of residuals. While this is not necessarily a problem for making predictions, it makes peeking at the coefficients pointless: their values won’t have much to do with the real correlation between features and target (the variance associated to their estimators being infinitely large). Use case 3: prediction with causal interpretation The relation between assumption # 3 and the problem of confounding may not be immediately apparent, but the intuitive idea is that the action of the confounding variable makes the independent variable and the residuals “move together” [ 2].

The authors cover numerous aspects of relationships: different dating markets, attraction strategies, to all sorts of practical questions which come up over the course of a relationship. Their approach throughout might be summarised as: decide on what you want; then look at the facts, logic, and best empirical knowledge for how it achieve it. Thinking like this, without ideological bias or lazily accepting common assumptions, is surprisingly rare and really refreshing. This book left no stones unturned when it comes to mastering the art of being in a relationship and understanding how to create and maintain a fulfilling one, resolving conflicts peacefully, and knowing how to handle life stresses without damage to your connection with your partner.

Many articles on linear regression and its assumptions look like long laundry lists. And these lists seem to have little connection to the way data scientists use linear regression in practice. Moreover, they give the wrong idea that — unless your data satisfy all the assumptions — you shouldn’t use a linear model.It's quite amusing to read overviews of common relationship models discussed more from the perspective of a historian or anthropologist than a contemporary arguing in favor of their own ideological team. This approach is much more useful because it mirrors the actual day-to-day work of a data scientist (we start from problems to solve and then think about the appropriate statistical toolbox, not the other way around!). TL;DR

Was there any way to detect from the data that our model was suffering from confounding bias? Yes, and that’s where assumption 3 comes in handy: Assumption # 4 — Homoskedasticity: the residuals have the same variance given any values of the features That’s why you must look for a partner who will love you as you are while encouraging you to reach higher. M ost often, the traits you already want to change will be the same ones your companion will want to help you improve, so this isn’t as hard as it sounds. Any group of people expected to work synergistically needs a system that structures their interactions. That system is “governance.” The Pragmatist’s Guide to Governance takes a first principles approach to exploring the ways governance structures affect the humans living under them (and vice versa), with a special focus on how human psychology interacts with the structures that facilitate our interaction with other people.This book focuses on instructing listeners on where, when, who, and how to look for potential dating and sex. It further gives instructions on how to best improve your relationship within your marriage. If you're not happy to leave things to chance, this book provides valuable insight into the who, what, where, when, and why’s of relationships. The advice is sensible and insightful.
