Nervous about the possibility of a miscarriage? The fear of miscarriage is one of the biggest fears women have during pregnancy. We all know someone whose had it happen to them, or maybe it’s happened to us. Yet, while miscarriage is common, it is not the likely outcome. Once a woman becomes pregnant the pregnancy is more likely to result in a baby than to end in a miscarriage. The Miscarriage Odds Reassurer is designed to remind us of this fact, and ease our fears.

Three-in-ten U.S. adults say they have ever used a dating site or app, but this varies significantly by age and sexual orientation.

Someone just forwarded me your election model with Elliott Morris and Merlin Heidemanns for the Economist. For the Bloomberg model — we used a linear increase in variance for the time to election, though something more elaborate might help! I know about your argument with Taleb against Nate. The whole thing frankly just seems pedantic to me. I agree that it might be pedantic — but the more uncertainty you have black swan or clock time , the wider than distribution for the terminal point gets.

So the probability of being greater than any value becomes 0. That was closer to our criticism of Nate: if there really was that much uncertainty black swan or pollster or news or time — the probability would have frozen. In finance terms, Biden winning is a binary option on the election date more realistically, a basket of binary options — so the more volatility there is, the closer to 0.

The Odds of Dating a Supermodel

Online dating sites are similar to previously analyzed matching markets in that logit specification to model the probability of receiving a reply.

I’ve got a better chance of dating a supermodel. Look at it this way: In a typical year, fewer than Americans are hit by lightning and killed. That gives me a 2. I’d have a better shot at catching dinner with a catwalk superstar like Heidi Klum, at least according to Gregory Baer in his soon-to-be-released book, Life: The Odds Gotham. It’s really quite simple: Assume all men are created equal, that they’re all heterosexual and that even the married ones would forgo their vows for an evening with Heidi.

That means there are million eligible bachelors in America and roughly 25 supermodels. Let’s also assume the ladies are heterosexual and available. And just to be conservative, let’s say a supermodel only dates five different men in a year. That would give the average American Joe an ,to-1 shot at landing the ultimate dream date. Of course, life isn’t fair, and if you’re a rock singer, professional athlete or movie star, you’ve got a much better chance of being seen with a magazine cover girl.

Alright, maybe my chances of dating a supermodel still stink, but it sure puts the risk of being hit by lightning into perspective. And if you’re a woman, you’ve got even less to worry about — a whopping 84 percent of lightning victims are men. Perhaps God likes women more, or perhaps women are just smarter when it comes to practicing common sense like stepping in from the rain, staying away from tall trees and bodies of water, advice your mother a woman probably gave you.

This can be extended to model several classes of events such as determining whether an image contains a cat, dog, lion, etc. Each object being detected in the image would be assigned a probability between 0 and 1, with a sum of one. Logistic regression is a statistical model that in its basic form uses a logistic function to model a binary dependent variable , although many more complex extensions exist.

In regression analysis , logistic regression [1] or logit regression is estimating the parameters of a logistic model a form of binary regression. In the logistic model, the log-odds the logarithm of the odds for the value labeled “1” is a linear combination of one or more independent variables “predictors” ; the independent variables can each be a binary variable two classes, coded by an indicator variable or a continuous variable any real value.

The corresponding probability of the value labeled “1” can vary between 0 certainly the value “0” and 1 certainly the value “1” , hence the labeling; the function that converts log-odds to probability is the logistic function, hence the name. The unit of measurement for the log-odds scale is called a logit , from log istic un it , hence the alternative names. Analogous models with a different sigmoid function instead of the logistic function can also be used, such as the probit model ; the defining characteristic of the logistic model is that increasing one of the independent variables multiplicatively scales the odds of the given outcome at a constant rate, with each independent variable having its own parameter; for a binary dependent variable this generalizes the odds ratio.

In a binary logistic regression model, the dependent variable has two levels categorical. Outputs with more than two values are modeled by multinomial logistic regression and, if the multiple categories are ordered , by ordinal logistic regression for example the proportional odds ordinal logistic model [2].

This document describes how to produce a customization of the TEI P5 schema. From the start, the TEI was intended to be used as a set of building blocks for creating a schema suitable for a particular project. This is in keeping with the TEI philosophy of providing a vocabulary for describing texts, not dictating precisely what those texts must contain or might have contained.

This means that it is likely , not just possible , that you will want to have a tailored view of the TEI. It is important to understand that there is no single DTD or schema which is the TEI; you always choose from the available modules there are currently 23 of them, listed in the module list below those that you want, with the caveat that the modules core , header , textstructure , and tei , when using RELAX NG should always be chosen unless you are certain you know what you are doing.

Components from these modules are referred to throughout the other modules, and hence these modules cannot be eliminated without careful adjustments. Although there is no default schema, TEI P5 does provide a number of example customizations which may very well meet your needs; these can be downloaded from the TEI web site or from within the Roma interface :.

For instance, once you have decided that your application will make use of the msdescription and linking modules, you may also want to. Below is a table of all of the TEI modules. More information about each one is given in the TEI Guidelines; each module corresponds to a single chapter. It is the language in which the TEI is itself defined, and which should also be used to express a customization of the TEI scheme.

The language developed over time as the TEI was put together, and one form of it was documented in the TEI Guidelines versions 3 and 4 ; unfortunately, that version of the markup was not what was actually used to write the TEI Guidelines, which diverged into a more complex scheme.

The Virtues and Downsides of Online Dating

Ten years ago a model of how states fail predicted that political instability in the US would “peak in the years around “. Its authors say it’s now pointing to “civil war”. In the early s, when Bill Clinton was in the White House and the United States looked unshakeable, the administration appointed Jack Goldstone to study how states fail. They meant other states; not the US. Few expected that his model would later predict their country’s collapse.

More recently, a plethora of market-minded dating books are coaching singles on how to seal a romantic deal, and dating apps, which have rapidly become the mode du jour for single people to meet each other, make sex and romance even more like shopping. The idea that a population of single people can be analyzed like a market might be useful to some extent to sociologists or economists, but the widespread adoption of it by single people themselves can result in a warped outlook on love.

M oira Weigel , the author of Labor of Love: The Invention of Dating , argues that dating as we know it—single people going out together to restaurants, bars, movies, and other commercial or semicommercial spaces—came about in the late 19th century. What dating does is it takes that process out of the home, out of supervised and mostly noncommercial spaces, to movie theaters and dance halls.

The application of the supply-and-demand concept, Weigel said, may have come into the picture in the late 19th century, when American cities were exploding in population. Read: The rise of dating-app fatigue. Actual romantic chemistry is volatile and hard to predict; it can crackle between two people with nothing in common and fail to materialize in what looks on paper like a perfect match. The fact that human-to-human matches are less predictable than consumer-to-good matches is just one problem with the market metaphor; another is that dating is not a one-time transaction.

This makes supply and demand a bit harder to parse.
