In MOM: Estimation and Testing of Hypothesis

Method of Moments Estimation of Negative Binomial distribution

Description

function to get the method of moment estimate(s) of negative binomial distribution

Usage

nbinom_est(
  data,
  size.known = FALSE,
  size = NULL,
  plot = TRUE,
  curvecol = "red",
  ...
)

Arguments

data	A numeric vector.
size.known	logical indicating whether the size of the binomial distribution is known or not.
size	integer valued parameter of binomial distribution.
plot	logical which controls whether the barplot of the data along with the probability curve of the theoretical negative binomial distribution with the estimated parameters.
curvecol	color of the theoretical probability curve
...	additional plotting parameters

Value

the estimated parameters by the method of moments of the data assuming the underlying distribution is negative binomial distribution

Examples

nbinom_est(rnbinom(1000,size=5,prob=0.2),size.known=TRUE,size=5)#no of successes known
nbinom_est(rnbinom(1000,size=10,prob=0.6))
