Arrange your x-values in … 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 ...
Webvariables. are the variables for which probability plots are created. If you specify a VAR statement, the variables must also be listed in the VAR statement. Otherwise, the variables can be any numeric variables in the input data set. If you do not specify a list of variables, then by default the procedure creates a probability plot for each variable listed in the … WebThe use of a normal probability plot allows a slightly more rigorous test of the normality assumption. A special plot, called a Q–Q plot (quantile–quantile), shows the observed …
