Multiple imputation of missing covariates when using the Fine-Gray model

survival-lumc/FineGrayCovarMI 26 May 2024

The Fine-Gray model for the subdistribution hazard is commonly used for estimating associations between covariates and competing risks outcomes.

Spectral analysis for noisy Hawkes processes inference

migmtz/noisy-hawkes-process 21 May 2024

Classic estimation methods for Hawkes processes rely on the assumption that observed event times are indeed a realisation of a Hawkes process, without considering any potential perturbation of the model.

Euclidean mirrors and first-order changepoints in network time series

TianyiChen97/Euclidean-mirrors-and-first-order-changepoints-in-network-time-series 17 May 2024

We describe a model for a network time series whose evolution is governed by an underlying stochastic process, known as the latent position process, in which network evolution can be represented in Euclidean space by a curve, called the Euclidean mirror.

Nonparametric Inference on Dose-Response Curves Without the Positivity Condition

zhangyk8/npDoseResponse 15 May 2024

In this paper, we present a novel integral estimator of the causal effects with continuous treatments (i. e., dose-response curves) without requiring the positivity condition.

A Generalized Difference-in-Differences Estimator for Unbiased Estimation of Desired Estimands from Staggered Adoption and Stepped-Wedge Settings

leekshaffer/GenDID 14 May 2024

By constructing an estimator using two-by-two difference-in-difference comparisons as building blocks with arbitrary weights, the investigator can select weights to target the desired estimand in an unbiased manner under assumed treatment effect homogeneity, and minimize the variance under an assumed working covariance structure.

Doubly-robust inference and optimality in structure-agnostic models with smoothness

matteobonvini/dr_inference 14 May 2024

While DRAL is generally not possible in the pure structure-agnostic class, we show that it can be attained in the new hybrid one.
