Research is deductive

Dr. Frank N. Stein developed an aggression measure and had his students fill out the measure and an already existing measure of aggression. He found that students’ scores on the two measures were moderately correlated. This is an example of

A time series was modeled as a Poisson hidden Markov model with three states.  The R output is below.  What is the estimated Poisson mean when in state 2?

ARCH models represent the residual series as a moving average process. 

Time series, cross-correlation, and ACF plots for series A and series B are below.  Series A leads series B. 

Consider the following time series plot: Does this time series appear to be a candidate for a hidden Markov model?  Explain. 

Time series, cross-correlation, and ACF plots for series A and series B are below.  The ACF plots indicate both series should be modeled as MA processes.

Based on the plots of the inverse roots of the AR and MA polynomials (or, the roots of the auxiliary polynomials), is the corresponding ARMA stationary and causal?  Is it invertible?

According to your textbook, what conflict style is characterized by couples who are highly assertive but have a great deal of concern for their partners as well?
