Population Data BC
เข้าร่วมเมื่อ 3 ก.พ. 2015
Population Data BC (PopData) is a multi-university, data and education resource facilitating interdisciplinary research on the determinants of human health, well-being and development.
We offer researchers access to one of the world’s largest collections of health care, health services and population health data, and a comprehensive education and training service on how to best use those data.
Linkage of data across sectors, such as health, education, early childhood development, workplace and the environment, facilitates advances in understanding the complex interplay of influences on human health, well-being and development.
The videos in this channel describe what we do and how researchers have used linked data to answer questions about the health and well-being of British Columbians. There are also instructional videos from our Education and Training Unit and presentations from conferences and other events.

Regression Discontinuity Design
มุมมอง 1.6K2 ปีที่แล้ว
Social policy and clinical care are filled with thresholds-people receive or don’t receive interventions or treatments based on factors such as income, test results, year of birth, and others. These thresholds are a potential source of quasi-randomization for strong observational studies. Regression discontinuity designs are a quasi-experimental research design that utilize these thresholds to ...
Record Linkage Methodology Under Fellegi-Sunter Paradigm, with Extensions
มุมมอง 2.2K2 ปีที่แล้ว
In 1969, Ivan Fellegi and Alan Sunter formalized a strategy for conducting probabilistic record linkage that had been developed previously. Included in this formalization was the demonstration that the scoring method used with this is optimal under certain assumptions. While other record linkage methods have been developed (including Bayesian-based ones) for large-scale linkages the Fellegi-Sun...

Sensing pedestrian flows for assessment of non-pharma policy interventions during COVID-19 pandemic
มุมมอง 4472 ปีที่แล้ว
Reducing the number of social contacts within a population has shown to be an effective measure to reduce the transmission of the SARS-CoV-2 virus. Some prominent non-pharmaceutical interventions (NPIs) have been, e.g., stay-at-home orders or closing schools/businesses. To assess changes in spatial mobility of the German population, sensor data of pedestrian flows in 49 metropolitan areas at 10...
Survival Analysis, Censoring and Time Scales
มุมมอง 2.7K2 ปีที่แล้ว
Survival analysis or time-to-event analyses have been popularized for making predictions about future events based on some exposure in the past. The methods are familiar to epidemiologists but also to actuarial scientists / insurance companies to estimate risk. This presentation will give a quick overview of Cox proportional hazard models, covering the assumption of independence of censoring, a...
Introduction to Statistical Disease Cluster Detection with Health Administrative Data

Disease processes have patterns and when disease varies in space, spatial patterns are produced. Identifying and quantifying patterns of disease in geographic areas may lead to a better understanding of why a disease occurs. This webinar will focus on some statistical cluster detection tests that can identify geographic areas with a higher prevalence of disease than expected.

Intro to Multistate Modeling Approaches for Analyzing Population-wide Health Administrative Data
Holy s***. I have been thinking about this problem for years and at least conceptually this seems like the solution to my problem. Very excited to try this out. Thank you!
Absolutely one of the best talks on youtube for survival analysis with competing risks. Cringed with a yikes at the interruption for questions at 55:40 when he is mid-sentence and mid-concept trying to get to cause-specific vs subdistribution etc.
Excellent presentation, thank you Prof. Sutradhar.
thanks alot
Great talk, tyvm!
Excellent presentation. Thank you for taking the time to explain all of this.
Hello, thank you for this great repo. But can you please tell me how can we get deduplicated enity for eg in fake_1000 dataset, let say I trained a model but now I want to use this to get deduplicated enityt/ cluster Id with most common values for each field. Please help me
ImportError: cannot import name 'exact_match' from 'splink.comparison_library' (C:\Python311\Lib\site-packages\splink\comparison_library.py) i am getting this issue how to resolve it?
Excellent presentation! Thanks so much for sharing!
Thanks for the presentation. We are trying to begin using Splink. Can you please let me know how to reach you the get some practice files.
the practice files are in the git repo
@@AshleyMillsTube Thank you so much. I will review them. Much appreciated.
an excellent lecture that saved me during epidemiology class. Thank you !
Amazed by how simple she made quantile regression to understand. Thanks!
any comparison to graph algorithms on the same use case?
Excellent, one of the best lectures ever on survival analysis and competing risks. Thanks Peter.

Thank you so much! great lecture
When using the msm procedure in R is censored modeled as a state, with time set to zero or is it not included as a state? Thanks
Excellent speech - Thank you. Which procedure in SAS are you using?
The SAS procedure is ‘proc phreg’.
@@populationdatabc1184 I know the proc phreg very well, but have do you model a Multistate model in proc phreg? Do you have an exampel or a paper descriping it? Thanks 🙂
Hi! Quick Question: what linker method corresponds to the chart displayed after training the u parameter (25:16)?

Outstanding presentation - thank you for posting!
Is it possible to get the r script?
Thanks so much. Excellent explanation, clear and understandable. Blessings
We were recently asked the following question from a past webinar participant: Question: "When we use IPTW as different time points to get the estimates, how will we pool them together to sum up a final hazard ratio?" Answer: This is done using a weighted model approach. For code and an example using Cox refer to academic.oup.com/aje/article/180/2/160/2739160
very nice presentation. I have a question about the competing risk in multi-state model. what kind of method is used in multi-state model, cause-specific or sub-distribution hazard model? Or another method?
Multistate models are a framework by which to examine event transitions over time. Survival models are simply a 2-state unidirectional multistate model. Competing risks models are also multistate models. If the question is about regression methods under a multistate framework, then both cause-specific and sub-distribution models may be implemented (similar to other multistate models, such as competing risks models).
Well explained. Thanks
Thank you! really useful ad helpful
je peux avoir le script (R) pour tester sur les données de mon pays??
Thank you very much. very useful.
This is one of the best lectures on Survival Analysis.
ppo
Really helpful, thanks!
how can we calculate sample size for computing risk regression model is it differ from survival technique or different? 2. can we apply competing risk with prediction model in asingle study?
The following is a reply from Dr. Peter Austin. 1. For a cause-specific hazard model, you can use methods that you would for a conventional Cox model. I haven’t seen examples of power calculations for subdistribution hazard models. 2. Can we apply competing risk with prediction model in a single study? I’m not entirely clear on what is meant by this question. One can develop and internally validate a model in a single study. However, one would want to subsequently validate the model in an external sample.
Thanks for this presentation. In the context of bank credit risk: If the primary event is time to loan default and say the the client closes and repays the loan account prior to loan maturity, i.e. loan is repaid and the account is closed (this event happened prior to loan default) and default is thus no longer possible. Is the account closure event a competing risk?
Yes, because default and prepayment are terminal states.
Really well explained! Thank you! Has helped me a lot!
I love this! Thank you so much
Wohoooo thank you!!!
