Robins's conjecture on continuous-time g-estimation for structural failure time models
Let structural nested accelerated/cumulative failure time models describe counterfactual failure times, and suppose treatment and covariate histories evolve as continuous-time proc…

Conjecture on simultaneous estimation of varying-coefficient functions
Let $\beta(t)$ and $\gamma(t)$ be the varying-coefficient functions in the model, and let $\hat{\beta}_c(t)$ denote the estimator obtained under the method described in the paper.…

Conjecture on efficient estimation in partially linear single-index longitudinal data models
The partially linear single-index longitudinal data model is estimated using the SGEE-based procedure and compared with the PULS estimators in terms of asymptotic efficiency. Effic…

Li–Liang proportionality conjecture for penalty parameters and standard errors
Let $\lambda_k$ be the tuning parameter associated with the covariate coefficient $\beta_k$ , and let the standard error of $\beta_k$ denote its estimated sampling uncertainty. Li–L…
