Statistical Methods and Analysis of Environmental Models

« Return


Students should be able to solve problems in SPSS and be able to understand all the basic concepts of statistics. On the other hand, should be able to estimate econometric models and to proceed to their statistical inference. To this must understand the theory behind the various techniques for estimating and validating the results also being able to use a statistical software, STATA, which allows practical implementation. Classes will be taught in computer lab.

Finally, it is intended to provide students with basic tools for modeling in the environmental area, as well as basic tools for the development of optimization models in the fields of nature conservation and environmental.


The program consists of three components: a review of basic statistical concepts, use of STATA in Linear Regression Models and Simulation Environment. In the first case will cover topics such as What is the statistic? Need for statistical review; How to quantify variability, Review of some statistical terms and concepts; statistical tests (parametric and nonparametric) and use the SPSS application. Thereafter it is intended that students understand The Simple Linear Regression Model: Estimation and Statistical Inference; Autocorrelation and Heteroscedasticity; Time Series; Instrumental Variables and Least Squares Two Steps and Limited Dependent Variable Models. D models population ecology and spatial models of cellular automata and fractals; Finally notions about modeling will be introduced. An introduction to linear programming and operational research will be made.
