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?"

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.

This example code describes the sample size and statistical power considerations in the design of the MARS Micro-Randomized Trial.

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.
