Supports four types of analyses: (1) proximal causal excursion effects, including weighted and centered least squares (WCLS) for continuous proximal outcomes by Boruvka et al. (2018) <doi:10.1080/01621459.2017.1305274> and the estimator for marginal excursion effect (EMEE) for binary proximal outcomes by Qian et al. (2021) <doi:10.1093/biomet/asaa070>; (2) distal causal excursion effects (DCEE) for continuous distal outcomes using a two-stage estimator by Qian (2025) <doi:10.1093/biomtc/ujaf134>; (3) mediated causal excursion effects (MCEE) for continuous distal outcomes, estimating natural direct and indirect excursion effects in the presence of time-varying mediators by Qian (2025) <doi:10.48550/arXiv.2506.20027>; and (4) standardized proximal effect size estimation for continuous proximal outcomes, generalizing the approach in Luers et al. (2019) <doi:10.1007/s11121-017-0862-5> to allow adjustment for baseline and time-varying covariates for improved efficiency.https://github.com/r-universe/tqian/actions/runs/37284317709Sat, 24 Jan 2026 22:00:02 GMTMRTAnalysis0.4.1successhttps://tqian.r-universe.devhttps://github.com/cran/MRTAnalysismrt-distal-causal-effect.Rmdmrt-distal-causal-effect.htmlExploratory Analysis for Micro-Randomized Trial (MRT): Continuous Distal Outcomes2025-08-29 08:41:172025-08-29 08:41:17mrt-proximal-causal-effect.Rmdmrt-proximal-causal-effect.htmlPrimary and Secondary Analysis for Micro-Randomized Trial (MRT): Proximal Outcomes2025-08-29 08:41:172025-08-29 08:41:17mrt-standardized-effect-size.Rmdmrt-standardized-effect-size.htmlStandardized Proximal Effect Size in MRTAnalysis2026-01-24 13:10:212026-01-24 22:00:02mrt-mediated-causal-effect-on-distal-outcome.Rmdmrt-mediated-causal-effect-on-distal-outcome.htmlTime-Varying Causal Excursion Effect Mediation in MRT: Continuous Distal Outcomes2025-09-09 07:20:312025-09-09 07:20:31t.qian@uci.edu (Tianchen Qian)Provides a sample size calculator for micro-randomized trials (MRTs) with binary outcomes based on Cohn et al. (2023) <doi:10.1002/sim.9748>. Also provides a power calculator when the sample size is input by the user.https://github.com/r-universe/tqian/actions/runs/37285262413Tue, 05 Dec 2023 03:31:12 GMTMRTSampleSizeBinary0.1.2successhttps://tqian.r-universe.devhttps://github.com/tqian/mrtsamplesizebinarysample-size-calcualtor-for-mrt.Rmdsample-size-calcualtor-for-mrt.htmlSample Size Calculator for Micro-Randomized Trials with Binary Outcomes2020-11-28 04:51:082023-12-02 04:21:50
