### Ph.D Seminar Courses

**STAT GR8220y. Topics in Spatial Statistics. 3 pts. **

This course will provide an overview of some statistical methods for spatial data. The focus will be mainly on spatial point processes and Gaussian random fields. We will study descriptive methods for spatial point data, models for spatial point processes and methods for fitting them to data. We will also look at inhomogeneous point processes, and bootstrap methods. For Gaussian random fields, we will discuss properties such as stationarity and isotropy. We will cover variogram estimation and fitting, kriging, fixed-and increasing-domain asymptotics, as well as methods for modeling non-stationary data. Examples will be taken from journal articles and various research projects covering a variety of fileds, such as astronomy, syndromic surveillance, epidemiology and fMRI.
