Stochastic square root of the Lundqvist-Korf diffusion process: Computational statistical inference and simulation aspects
A. El Azri, A. Nafidi, R. Gutiérrez Sánchez, E. M. Ramos Ábalos
This work presents a new inhomogeneous stochastic diffusion process, defined by the square root of the inhomogeneous stochastic Lundqvist-Korf diffusion process, which we term the stochastic square root of the Lundqvist-Korf diffusion process. Using a transformation in diffusion process and by applying Itô's calculus. First, we establish the probabilistic characteristics of the process, such as its analytic expression, after which we determine the transition probability density function and the mean functions. The parameters present in the process are estimated by maximum likelihood method using discrete sampling. Due to the problem of maximum likelihood estimation of the parameters, the resulting system of equations is quite complex and the simulated annealing algorithm is proposed to solve it. Finally, we apply the proposed process and statistical results obtained to a simulated data.

Visit Alhambra
Tomorrow, Thursday, we will visit the Alhambra. 1. At 7:00 p.m., buses will start leaving from the door of the Hotel Granada Center (in front of the door of the Faculty of Sciences) 2. Upon arrival, groups with guides will be organized. 3. There will be groups in English language. These groups will wait at the destination until the arrival of all buses. 4. After the visit to the Alhambra we will walk to the Carmen de los Mártires to have a cocktail. 5. On the way back, we can go back by bus, which will leave from the same place where they left us at the Alhambra. 6. Although the way to the Alhambra by bus seems long, it really is close to the city. We invite you, whoever wishes, to go down for a pleasant walk. 7. Do not forget to take your Alhambra ticket and your identity card or passport. The document must be the same whose number matches the ticket number you have.
