mixed SCORE || STUDENT:TIME

I wish to estimate SLOPES and INTERCEPTS for each STUDENT to attain a data set such as

STUDENT TIME    SCORE   RANDOMSLOPE RANDOMINTERCEPT
1   1   9       
1   2   11      
1   3   7

3   3   9       
4   1   14      
4   2   6   

However I am insure of how to store the intercept and slope for every STUDENT


Solution

  • The reference here may be helpful, for random slope in Chapter 4 (https://errickson.net/stata-mixed/random-slopes.html) and for predicting random in Chapter 3.3 (https://errickson.net/stata-mixed/fitting-linear-mixed-models.html). The reference uses "predict rintercept, reffects" to get the random intercepts. Also, the postestimation part of the Stata manual (https://www.stata.com/manuals/me.pdf) page 543 - page 546 is relevant for you to figure out the definition of re1 and re2.
