    how to deal with missing values ?

    I have around 80 measurements done for 30 participants over 10 different time points.
    There is some missing data:

    1- some participants have missing values for some measurements.
    2- Some participants have measurements done over X time points where X < 10.

    I want to check if there was an improvement in certain measurements over time. But how can I deal with missing values?
    I cannot use default values. and I cannot ignore participants who have missing values, otherwise I might end up at the end with a very small number of participants.

    help is appreciated.

    You have to first devise a case for missingness pattern? At random, monotonic, etc.

    Why do you have missing data?
