World-System(1950-2000) A Deep Dive into the Iranian State Space
In prior blog postings, I have usually displayed only the first three state variables of a DCM ( Dynamic Components Model ). There are three reasons: (1) Typically, the first three state variables explain at least 90% of the variation in the underlying indicators. For example, in Iran (see the Measurement Matrix below in the Notes) the first three components ( IR1 , IR2 , IR2 ) explain 98% of the variation in the underlying indicators. (2) Also, typically, the first state variable describes overall growth in the system and the next two state variables describe historical cycles and feedback controllers ( here and here ). And, (3) it is difficult to explain the dynamic path of state variables in more than three dimensions. However, interesting dynamics are observed in the lower-order state variables. In the graphic above, the state space IR4 , IR5 and IR6 is displayed. The graphic above shows the unstable, cyclical dynamic state-space interaction between IR4 =( a Popula...
