Hi folks, I have some data where I have to investigate with a suitable QQ-plot wheter or not the measurement erros are normally distributed. The distributed data are form the residuals of a lineair regression, that can be considered as aproximations of the actuel measurement errors. This is the graph: http://r.789695.n4.nabble.com/file/n4633819/QQplot.jpg
How can I recognize, with reference to the graph, if the errors are normally distributed or not. And with that conclusion in mind, is there some relationship between those variables?
