Modeling Volatility under Normal and Student-t Distributional Assumptions (A Case Study of the Kenyan Exchange Rates)
http://pubs.sciepub.com/ajams/2/4/1
{^{i}^{}} models for modeling daily changes in logarithmic exchange rates (log Rt^{{}^{ii}^{}}) are analyzed here. One is based on modeling the data on assumption of normal distribution and the other is based on the standardized student-t distribution. In particular, the (log Rt) of USDKES^{{}^{iii}^{}}, EUROKES^{{}^{iv}^{}}^{ }and GBPKES^{{}^{v}^{}} are considered. For each assumption EGARCH is fitted, with varying numbers of parameters, and attempt to replicate the empirical (log Rt) sequence via simulation. Assessing the fit of each model, it is concluded that the families of EGARCH models with t-innovations adequately reflect the empirical nature of the (log Rt) sequence and therefore provides a better prediction model.]]>

Total Domination Subdivision Number in Strong Product Graph
http://pubs.sciepub.com/ajams/2/4/7
D of vertices in a graph G(V,E) is called a total dominating set if every vertex v∈V is adjacent to an element of D. The domination subdivision number of a graph G is the minimum number of edges that must be subdivided in order to increase the domination number of a graph. In this paper, we determine the total domination number for strong product graph and establish bounds on the total domination subdivision number for strong product graph.]]>
