**Title***An Introduction to Markov Switching Models***Abstract**- Markov switching models are a natural extension of the finite mixture models, which could be useful when error source are potentially from multiple different distributions and its label is missing. I will give a short introduction on the basics of the finite mixture models and Markov chain, and combine the two to introduce Markov switching model and ways of estimation and inference. Lastly, I will briefly explain my current work involving Fisher information matrix of Markov switching models.

**Title***Finite Element Method in 1 Dimension***Abstract**- In this talk we will discuss about the Finite Element Method in approximating the solution to a boundary value problem in 1-D on the interval [a,b]. By converting the problem into the variational form, we will be able to discretize it and seek for an approximation of the solution in a finite dimensional subspace. This is obtained by partitioning the interval [a,b] and approximate the solution in each subinterval using basis functions of the finite dimensional subspace.
