Wide-format state sequences of student engagement over 15 weekly
observations. Each row is one student; columns 1..15
hold the engagement state for that week. States: "Active",
"Average", "Disengaged". Missing weeks are NA.
Format
A character matrix with 138 rows and 15 columns, one row per
student. Columns are named "1".."15" (the week). Entries
are one of "Active", "Average", "Disengaged", or
NA; NA runs at the end of a row mark drop-out, which the
right-censored sequence verbs (actor_endpoints,
mark_terminal_state) are built to read.
