beta_est: Method of Moments Estimation of Beta distribution

In MOM: Estimation and Testing of Hypothesis

Method of Moments Estimation of Beta distribution

Description

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

Usage

beta_est(
  data,
  unknown = c("shape1", "shape2", "both"),
  shape1 = NULL,
  shape2 = NULL,
  plot = TRUE,
  curvecol = "red",
  ...
)

Arguments

data	A numeric vector.
unknown	A character string specifying which parameter is (are) unknown to the user.
shape1, shape2	Non-negative parameters of the Beta distribution.
plot	logical which controls whether the histogram of the data along with the density curve of the theoretical beta distribution with the estimated parameters.
curvecol	color of the theoretical density curve
...	additional plotting parameters

Value

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

Examples

beta_est(rbeta(1000,shape1=2,shape2=1),unknown="shape2",shape1=2)#shape1 is known
beta_est(rbeta(1000,shape1=2,shape2=1),unknown="shape1",shape2=1)#shape2 is known
beta_est(rbeta(1000,shape1=2,shape2=1),unknown="both")#both will be estimated
