I followed children born 2010 and 2011 for three years collecting data on various symptoms, such as ADHD, externalizing behavior problems, emotion dysregulation etc. I started my data collection when the children where finishing their last year at preschool and ended my data collection when they finished 2nd grade in elementary school. I used both online questionnaires which parents and teachers answered about the children and also diagnostic interview I administered to parents of children who where reported above the cut-off score on any of the online questionnaires.</P><P>&nbsp;</P><P>Now I want to explore if emotion dysregulation at time 1 is predicting behavior problems at time 3. What do you think is appropriate analysis for that - I have been looking at, for example, Latent Growth Model, Partial Least Squares, Discriminant Analysis Functioning. Should I be looking at something else and should I focus on linear models or non-linear models?</P><P>&nbsp;</P><P>Thank you for reading my looooong post!</P> Thu, 18 Jul 2019 13:52:02 GMT https://communities.sas.com/t5/Statistical-Procedures/What-procedure-would-best-fit-my-longitudinal-data/m-p/574569#M28235 Marion83 2019-07-18T13:52:02Z https://communities.sas.com/t5/Statistical-Procedures/What-procedure-would-best-fit-my-longitudinal-data/m-p/574939#M28248 <P>If you are in Pharmacy field , try PROC GLIMMIX or PROC MIXED for longitual data .</P> Fri, 19 Jul 2019 13:31:09 GMT https://communities.sas.com/t5/Statistical-Procedures/What-procedure-would-best-fit-my-longitudinal-data/m-p/574939#M28248 Ksharp 2019-07-19T13:31:09Z https://communities.sas.com/t5/Statistical-Procedures/What-procedure-would-best-fit-my-longitudinal-data/m-p/574950#M28249 Thank you very much - I will look into that <span class="lia-unicode-emoji" title=":slightly_smiling_face:">🙂</span> Fri, 19 Jul 2019 14:05:06 GMT https://communities.sas.com/t5/Statistical-Procedures/What-procedure-would-best-fit-my-longitudinal-data/m-p/574950#M28249 Marion83 2019-07-19T14:05:06Z
