Hi
I'm hoping someone might be able to kindly offer advice re some growth models I'm running at the moment (using SPSS mixed)
I've seen in some papers reporting quadratic relationships in unconditional growth models, that they report the exact ages at which the trajectories change and I'm just wondering how one calculates this.
Also I've seen papers model plots of (non-linear) trajectories as a function of one or two moderators (i.e. a 2 or 3 way cross-level interaction). I'm just wondering how one actually does these plots within SPSS (or is there additional software)?
Many Thanks
Tom
When working with many factors,In teraction effect is important.so. We must fit models accordingly
Honestly I have worked with SPSS for more than 5 years and found out that First you have to sit and learn the videos on you tube to found more options to finish your work. Some times you have to use separate SPSS Data entry for certain groups as they are difficult to separate according to ages or others you have to be expert in using SPSS.
Separate the Data of different ages on different SPSS Sheets then you can do Data Analysis and Diagramatic Presentation easily. One must sit down and spend time to learn the options on SPSS sheet Software. Regards
My Favorite text on Growth models is Chapter 6 of Srivastava and Carter. See the link below:

Another good book on the topic is by M. S. Srivastava. The link is:

Hi Tom
1. In the literature, there are several growth models exist. Some of which:
The Aggregate Production Function
The Basic Growth Model
....
2. The framework is based on five equations as given below:
· An Aggregate Production Function Equation
· The Saving Equation
· The Relation between Saving and Investment
· Change in Capital Stock over Time
· The Labour Supply Equation
3. Several papers have been published and discussed different growth models. Please refer to:
