WebUse the normal probability plot of the effects to determine the magnitude, direction, and the importance of the effects. On the normal probability plot of the effects, effects that are further from 0 are statistically significant. The color and shape of the points differ between statistically significant and statistically insignificant effects. Webqqplot (x) displays a quantile-quantile plot of the quantiles of the sample data x versus the theoretical quantile values from a normal distribution. If the distribution of x is normal, then the data plot appears linear. qqplot plots each data point in x using plus sign ( '+') markers and draws two reference lines that represent the theoretical ...
