Learn statistics and R

I love stats because I am fas­ci­nat­ed by its pow­er in bring­ing order out of chaos, to elu­ci­date pat­terns and to test hypothe­ses for gain­ing new knowl­edge. This is a site for you who want to learn sta­tis­ti­cal the­o­ry for con­duct­ing and under­stand­ing the back­ground of sta­tis­ti­cal analy­ses. The site is thus best suit­ed for stu­dents and researchers with an inter­est of learn­ing sta­tis­tics. I will also show you how to do it in the open source sta­tis­ti­cal soft­ware R. For­get about expen­sive sta­tis­ti­cal tools such as SPSS or SAS.

The web site con­tains a series of arti­cles where I have gath­ered my insights from years of expe­ri­ence from applied sta­tis­tics. The goal has been get down to the core, the key essen­tials to help you on the way. Use the con­tent of this site as a com­ple­ment to exist­ing lit­er­a­ture and course mate­r­i­al.  You will also find con­crete exam­ples, R code and tutorials.

I have con­struct­ed this web­site because I love to share knowl­edge and exper­tise. I hope you will find this site useful.
