WebWe can compute it by finding the roots, or zeros, of this equation: Δ p = α p + β p 2. where α and β are the parameters of the model. If we rewrite the right-hand side like this: Δ p = p ( α + β p) we can see that net growth is 0 when p = 0 or p = − α / β . So we can compute the (non-zero) equilibrium point like this: WebStructural equation modeling analysis of social support, coping strategies, depression and suicidal ideation among people living with HIV/AIDS in Changsha, China.
