Matt:
Be sure and also look at recent
studies in social and personality psychology which have dealt with this issue
in great detail.

Subject: Time series analysis with random intervals for data points
Hello list.
I have a query regarding the
appropriateness of using time series analysis when the data points are
collected at random intervals. My study is looking at fluctuations in mood
throughout the day and trying to link it to gym attendance and exercise. Each
participant will fill out a brief survey via PDA, 7-8 times per day for the
duration of one week. The PDA is set to randomly signal participants to
complete the survey, but the testing sessions are within the hours of 8am to
10pm.
As the time points will be randomly
selected by the PDAs and given that no data will be collected between 10pm and
8am, is it still possible to use time series analysis to determine the extent
to which exercise/gym attendance influences mood?
Thanks in advance,
Matt.
