seq_br_norm_mean

Description

Sequential approach to Get Bounded Risk Point Estimation for normal random variables. Calculates the risk for a normal random variables.

Usage

seq_br_norm_mean(
  data = NULL,
  A,
  k,
  w,
  pilot = FALSE,
  verbose = FALSE,
  na.rm = TRUE
)

Arguments

data	The data for which to calculate the bounded risk point.
A	The loss function constant.
k	Controls whether the absolute error or squared error is used. K=1 uses absolute error, K=2 uses squared error.
w	The risk bound.
pilot	Should a pilot sample be generated. True/False value. default value is FALSE.
verbose	Should the criterion value be returned, True/False value, default value is FALSE.
na.rm	This parameter controls whether NA values are removed from the data prior to calculation. Default is TRUE.

Value

The calculated risk, the sample size, mean, standard deviation, and an indicator of if the criterion was satisfied.

Examples

pilot_ss <- seq_br_norm_mean(A=2, k=1, w=0.4, pilot=TRUE)  # k=1 absolute error,
# k=2 squared error
SLS <- rnorm(pilot_ss, mean=2, sd=3)
seq_br_norm_mean(data=SLS, A=2, k=1, w=0.4, pilot=FALSE)
