Workshop Description

The Third Workshop on Higher-Order Asymptotics and Post-Selection Inference (WHOA-PSI)^{3} seeks to build upon the success of the first workshop and second workshop, by presenting the latest developments in post-selection inference, and discussing how tools from higher-order asymptotics can both elucidate important properties of post-selection inference procedures, as well as suggest new directions which may ultimately yield more accurate small-sample performance. The workshop format is intended to encourage collaboration and lively discussion, and to give a voice to all participants with online discussion forums (a result of a successful experiment from the first two workshops). More specific details will soon be posted below. Contact: Todd Kuffner, email: kuffner@wustl.edu

This conference supports the Welcoming Environment Statement of the Association for Women in Mathematics (AWM).

Registration Details
Click here to register. The registration fee is $320. This includes all breakfasts, lunches, coffee breaks, and the banquet dinner on Saturday September 8th. The deadline to register has been extended until August 31st at 11:59pm US Central time. Spaces are limited, and registration may close sooner if the capacity is reached, so it is recommended that you register early. The number of available places is listed at the bottom of the registration page.

Dates, Times, and Location

The workshop is a full 3 days. The talks will begin around 8:30am on Saturday September 8th, and will end by 5pm on Monday September 10th, 2018. The workshop will take place at a conference center on the campus of Washington University in St. Louis in St. Louis, Missouri, USA.

Availability of Funding for Junior Participants

We have allocated all available NSF funds to registered participants. Unfortunately there is no additional financial support available.

Poster Session

There will be one or two poster sessions. Anyone wishing to present a poster should indicate this on the online registration form. The topic of the poster should be related to the content of the workshop. Please check with the organizers if you are unsure about the suitability of your poster topic. The deadline for titles and abstracts is August 14th. More details about the poster session will be emailed to poster presenters after registration closes.

Lodging Information

All workshop participants will have to make their own lodging arrangements. The Knight Center (the location of the workshop on campus) is holding 66 guest rooms at a special rate of $119/night for each of the 4 nights Sept 7, 8, 9, and 10. These rooms are available on a first-come, first-serve basis and the deadline to book a room is August 17th. Each of these rooms has a queen-size bed, and the price includes parking. To reserve your room, please call the Knight Center at +1 314-933-9400 and use the block code `Mango Statistics' to book one of the rooms being held for workshop participants. Alternatively, some other nearby hotels include the Clayton Plaza Hotel and the Moonrise Hotel.

Local Information

For those arriving early or thinking about staying longer, St. Louis is a lovely place to visit. Besides the iconic Gateway Arch and the nearby Old Courthouse which houses exhibits on the Dred Scott case, St. Louis has a stunning botanical garden, a high density of good restaurants (BBQ is a specialty), and is close to many rivers (Missouri, Mississippi and Meremac) which are great for float trips. There are many nearby parks and nature reserves which are excellent for hiking, as well as a wolf sanctuary. Mark Twain's boyhood home lies an hour north of the city. Anheuser-Busch is headquartered in St. Louis and offers tours of the brewery (requires advance booking due to popularity). For those unfamiliar with the institution, Washington University in St. Louis is a leading national research university, ranked 23rd in the world in the 2016 Academic Ranking of World Universities. Our statistics presence is concentrated in the Dept. of Mathematics. You are encouraged to look around this beautiful campus on the western edge of St. Louis, which faces Forest Park, the site of the 1904 World's Fair and home to the Saint Louis Zoo and Saint Louis Art Museum (both free admission, walking distance from campus).
