Description

Stratified Sampling Method

Usage

SI.SSM(h, from, to, level, N)

Arguments

h

Density function to be integrated

from

The start point

to

The end point

level

Stratification, number of intervals

N

The number of trials

Value

I

%% ~Describe the value returned %% If it is a LIST, use %% \item{comp1 }{Description of 'comp1'} %% \item{comp2 }{Description of 'comp2'} %% ...

Examples

# NOT RUN {
## To integrate exp(x) from -1 to 1
set.seed(0)
h <- function(x){
    exp(x)
}
N <- 100000
SSMresult <- SI.SSM(h,-1,1,10,N)
I4 <- SSMresult[[1]]
VarI4 <- SSMresult[[2]]
