Sample size calculations for the Sense2Stop Study: A stratified, micro-randomized trial
This example code calculates the minimum sample size for Sense2Stop, a 10-day, stratified micro-randomized trial. Study participants wear a chest and wrist band sensors that are used to construct a binary, time-varying stress classification at each minute of the day. The intervention is a smartphone notification to remind the participant to access a smartphone app and practice stress-reduction exercises. Intervention delivery is constrained to limit participant burden (a limit on the number of reminders sent) and to times at which the sensor-based stress classification is possible. The trial was designed to answer the questions: "Is there an effect of the reminder on near-term, proximal stress if the individual is currently experiencing stress? And, does the effect of the reminder vary with time in study?"

The Self-Relevant Appeals to Engage in Self-Monitoring of Alcohol Use Micro-Randomized Trial
This example code describes the curation and analysis of data from a micro-randomized trial (MRT) among college students. The MRT was designed to estimate the effect of just in time digital prompts (reminders) on engagement in self-monitoring for alcohol use.
Power calculation for the Mobile-Assistance for Regulating Smoking (MARS) Micro-Randomized Trial
This example code describes the sample size and statistical power considerations in the design of the MARS Micro-Randomized Trial.
Calculate the sample size and power for a Micro-Randomized Trial with a continuous proximal outcome
This web applet calculates the minimum sample size necessary for a Micro Randomized Trial with continuous proximal outcome.

Estimate the proximal and distal causal effects of a just-in-time intervention component on a continuous outcome using data from a Micro Randomized Trial
This code is used to estimate the causal effect of a just-in-time intervention component on the mean of a continuous proximal or distal outcome using data from an MRT.
