A Tutorial on Regularized Partial Correlation Networks
Sacha Epskamp, Eiko I. Fried
https://arxiv.org/pdf/1607.01367
Recent years have seen an emergence of network modeling applied to moods, attitudes, and problems in the realm of psychology. In this framework, psychological variables are understood to directly affect each other rather than being caused by an unobserved latent entity. In this tutorial, we introduce the reader to estimating the most popular network model for psychological data: the partial correlation network. We describe how regularization techniques can be used to efficiently estimate a parsimonious and interpretable network structure in psychological data. We show how to perform these analyses in R and demonstrate the method in an empirical example on post-traumatic stress disorder data. In addition, we discuss the effect of the hyperparameter that needs to be manually set by the researcher, how to handle non-normal data, how to determine the required sample size for a network analysis, and provide a checklist with potential solutions for problems that can arise when estimating regularized partial correlation networks.

Recent developments on the performance of graphical LASSO networks
This post was written by Sacha Epskamp, Gaby Lunansky, PIa Tio and Denny Borsboom, on behalf of the Psychosystems lab group. Currently, many network models are estimated using LASSO regularization. For ordinal and continuous variables, a

2020 Summer School in Social Neuroscience and Neuroeconomics
Reminder that applications are due by January 1 for the 2020 Summer School in Social Neuroscience and Neuroeconomics (June 8-13) hosted at Duke: https://www.socialneuroecon.school/2020
There is no cost to attend the school; registration, lodging, and reasonable travel expenses will be covered for all attendees. The school is open to post-baccs, grad students, post-docs, and junior faculty.
Priority will be given to individuals with research programs currently focused on improving health and well being in old age or who have plans to extend their work into this area (the school is funded by a grant from the National Institute on Aging). Individuals from backgrounds that are underrepresented in science are strongly encouraged to apply.
If you are hesitant to apply because travel is complicated while you have an infant or small children, we will do everything we can to accommodate you. If there is interest, we will provide child care during the days and can provide space and time during the events for nursing and/or other childcare-related activities. If needed, we can express ship your pumped milk home to an infant using Milk Stork.
If you missed the initial announcement, don’t worry - the application is one paragraph and we don’t request recommendation letters unless there is a multi-way tie for a spot. It should take about 20 minutes or less to apply, If you are local (Duke, UNC, etc) and won’t require lodging, you still need to complete an application to be able to attend.
Hope to see you this summer at Duke!

😱 One more thing: the doctoral track.
If you are talented and your grades are excellent, you can apply to the doctoral track where your final target is not the master’s degree but a PhD; your studies are tailored towards that goal and you’ll get to spend time as intern in our research groups, with the aim of publishing the first journal article(s) of your thesis already before you get the master’s degree.
So, what are you waiting for? Apply here! The deadline is on Jan 3rd, 2020.

🎯 آیا مدلهای ریاضیاتی بالاخره میتوانند موفق به پیشبینی تاریخ شوند؟
— مورخان همیشه به کسانی که خواستهاند تاریخ را به الگو تبدیل کنند بدبین بودهاند. این بدبینی مشروع است؟
📍پیشبینی وقایع آینده شاید بزرگترین آرزوی علوم اجتماعی باشد. چیزی که تلاش برای رسیدن به آن تا به امروز چندان حاصلی نداشته و همین باعث شده تا بسیاری از پژوهشگران علوم تاریخی و اجتماعی، از این آرزو دست بردارند. بااینحال، هنوز کسانی پیدا میشوند که دلشان بخواهد بخت خودشان را در این مسیر آزمایش کنند. یکی از آنها پیتر تورچین است. زیستشناسی علاقهمند به ریاضیات که با کلاندادهها، معادلات آماری و تکنیکهای محاسباتی جدید سراغ تاریخ آمده است و ظاهراً حرفهایی برای گفتن دارد.
