sample.moments function

Estimation of sample moments

Estimation of sample moments.

sample.moments(x, na.rm = FALSE, raw = T, central = T, coef = T, order = 1:4)

Arguments

• x: a numeric vector of values
• na.rm: a logical value indicating whether NA values should be stripped before the computation proceeds
• raw: logical - calculate raw moments?
• central: logical - calculate central moments?
• coef: logical - calculate coefficients (coefficient of variation, skewness and kurtosis)?
• order: vector of integers - raw moment orders

Examples

library(CoSMoS)

x <- rnorm(1000)
sample.moments(x)

y <- rparetoII(1000, 10, .1)
sample.moments(y)
