probplot
plots probability plot for a vector of values, given distribution specifications. Confidence intervals and a legend can be plot too.
probplot(x, distribution, theta, confintervals = FALSE, confidence = 0.95, name = deparse(substitute(x)))
x |
a vector of values. |
distribution |
character specifying distribution to plot |
theta |
vector of parameter. Estimated by the function if left missing |
confintervals |
logical item, indicating wherether confidence interval have to be plotted or not. |
confidence |
confidence 1-α level. |
name |
name of variable plotted. |
(x,y) values represent respectively original data and corresponding quantiles of theorethical estimated distribution. If the theoretical distribution fits data well, values should lies around the straight line plotted.
