Admitted to PhD-studies. Basic knowledge of statistics and R

Objectives

This course is part of the course theme Advanced Statistics in Practice and aims to fill potential knowledge gaps by preparing students to analyze, interpret and report their data using the most up-to-date methods in R. Special attention will be given to discussion of questions springing from the students’ own work and the biological interpretation of data. The course is intended to deepen the students’ understanding of all aspects of ecological inferences, not as a cookbook of "how to". Learning outcomes 1-Demonstrate the ability to identify relevant functions and packages in R for analyzing their own datasets. 2-Analyze data using R, including reporting advanced statistics, univariate and multivariate modelling and generation of graphs. 3-Interpret, think critically and draw conclusions on data analysis results.

Content

Unit 2: GIS and spatial analysis. February 15 and 18 2021 . Teachers: Alistair Auffret (alistair.auffret@slu.se) and Mohammad Bahram (mohammad.bahram@slu.se). 1.Intro: Why GIS in R? Which packages? 2.Vector analysis: Buffer zones, Intersections, Summary statistics etc. 3.Raster analysis: Overlays, Reclassification, Raster calculator 4.Spatial autocorrelation and its effect on your results, strategies and methods for accounting or using spatial autocorrelation 5.Analysing spatially-structured ecological data The course activites includes initial readings, classroom discussions, hands-on activities, followed by home exercises. This unit corresponds to one theme/workshop and is planned for two half days, equaling one credit (ca 27 hours of work for the PhD student). Example datasets will be provided but students could use their own datasets as well.
