Is it possible to meaningfully use normal probability plot - or Q-Q graph - in genetic association study when comparing polymorphism of genes with the sport performance? Or is it a dead end in the description of the results?
Moran et al, 2007, have used such graphic description (Eur J Hum Gen, 2007, 15, 88-93, Figure 2). Do you know any other use of Q-Q plot in similar research? Thank you.
Q-Q plot plotted quantile of vertical axis v.s. quantile of horizontal axis, but normal probability plot plotted the probability distribution of horizontal variable against of normal distribution, in other hand normal probability plot is a tools for checking normal assumption. Please be mention your exact question with more details.
Shayan, thank you for the correct note. I mean, either one or the other type of chart. In principle, the point is, if someone of esteemed colleagues have knowledge about the use of this type of chart in that type of study.
It is true, Q-Q plot can be have different applications in each type of study. If your aim is prediction of trend between genes over time, it will be better that you use smoothing or piecewise analysis. Good luck.
