qqPlotDemo {CarletonStats} | R Documentation |
Demonstrate the normal quantile-quantile plot for samples drawn from different populations.
qqPlotDemo(n = 25, distribution = "normal", mu = 0, sigma = 1, df = 10, lambda = 10, numdf = 10, dendf = 16, shape1 = 40, shape2 = 5)
n |
sample size |
distribution |
population distribution. Options are |
mu |
mean for the normal distribution. |
sigma |
(positive) standard deviation for the normal distribution. |
df |
(positive) degrees of freedom for the t-distribution. |
lambda |
positive rate for the exponential distribution. |
numdf |
(positive) numerator degrees of freedom for the chi-square distribution. |
dendf |
(positive) denominator degrees of freedom for the chi-square distribution. |
shape1 |
positive parameter for the beta distribution (shape1 = a). |
shape2 |
positive parameter for the beta distribution (shape2 = b). |
Draw a random sample from the chosen sample and display the normal qq-plot as well as the histogram of its distribution.
Returns invisibly the random sample.
