*AIM* Establish a prior distribution to represent expert opinion in a multinomial model setting
3/n
*CHALLENGE* Find meaningful assessment tasks to determine parameter values in the prior distribution, & develop theory to determining these values
*METHOD* Sampling model from a multinomial logistic regression & a multivariate normal dist. to represent expert opinion
4/n
*RESULTS* A method which address the 👆🏽 challenges & interactive easy‐to‐use software which is freely available!

Kim et al. (2020) assessing the health effects of power plant emissions through ambient air quality doi.org/10.1111/rssa.1…
*AIM* Offer a novel statistical evaluation of key causal relationships between emissions, ambient pollution and health
6/n
*GAP* Systematic evidence of health impact assessments of emissions from coal power plants exist; yet assumed causal relationships between emissions, ambient pollution and health have remained empirically unverified
*METHOD* Bayesian methods and causal mediation analysis
7/n
*RESULTS* A unified epidemiological methodological framework integrating causal inference with direct measurements of coal emissions, pollution transport, ambient pollution and human health
8/n
Galbraith et al (2020) quantifying the association between discrete event time series with applications to digital forensics doi.org/10.1111/rssa.1…
*AIM* Quantify associations between two discrete events exhibit temporal clustering
9/n
*METHODS* A non-parametric approach is used to investigate various score functions to quantify association, inc. marked point processes and summary statistics of inter-event times
10/n
*RESULTS* Two techniques are proposed:
1] a pop.-based approach to calculating score-based likelihood ratios when a sample from a relevant
population is avail.
2] a resampling approach to computing coincidental match prob. when only a single pair of event series is avail.
11/n
Stay tuned - next 3 articles TOMORROW! and more! 🙌🏽

*CONTEXT* Standard network meta‐analysis & indirect comparisons combine aggregate data from multiple studies, assuming that any effect modifiers are balanced across pops. & often incurring in aggregation bias 2/n
*AIM* Propose a new method extending the standard network meta‐analysis framework
*METHOD* Use of general numerical approach using quasi‐Monte‐Carlo integration 3/n
