Data Analytics

Hello! I am looking for someone to consult with me on a epidemiological data paper. My dataset comes from repeated, longitudinal measurements on participants cigarette use. Each day of the 21-day study, each participant provided information on how many cigarettes they smoked that day (CPD). There is some missing data. So my dataset has around 80 unique ids, with 10-21 observations per day, reflecting days 1-21 of the study. I have developed a mixed effects model to predict CPD. What I need to do now is predict - for each person and each day - CPD based upon the model. I imagine a dataset with 80 unique IDs, 21 observations per ID, with one column for actual CPD and another column for predicted CPD. I will ultimately use these data points to calculate a mean absolute deviation for each person. I use R and I am not sure how to get this information. Ideally, we can work together via screenshare to address this issue.
