Performs Cramer-von Mises test for the composite hypothesis of exponentiality, see e.g. Henze and Meintanis (2005, Sec. 2.1).
1 | cvm.exp.test(x, nrepl=2000)
|
x |
a numeric vector of data values. |
nrepl |
the number of replications in Monte Carlo simulation. |
The Cramer-von Mises test for exponentiality is based on the following statistic:
ω^2_n =\int_0^∞ (F_n(x)-(1-\exp(-x)))^2\exp(-x)dx,
where F_n is the empirical distribution function of the scaled data Y_j=X_j/\overline{X}. The p-value is computed by Monte Carlo simulation.
A list with class "htest" containing the following components:
statistic |
the value of the Cramer-von Mises statistic. |
p.value |
the p-value for the test. |
method |
the character string "Cramer-von Mises test for exponentiality". |
data.name |
a character string giving the name(s) of the data. |
