Hi folks, I am starting to dig in a new field, in which my institute (leibniz-psychology.org) has access to smartphone data which implies a stream of behavioral data.

Being myself rather experienced in cross-sectional data, I would like to have some suggestions how to approach such data with regard to

a) data management (e.g., sampling or aggregating)

b) and analysis.

With regard to #b I am thinking of something as time-series modeling or growth curve modeling but have no further clue.

If your post some beloved referenes/introductions or have further tips, I am looking forward to know them.

With best regard
