trapzc: Trapezoidal formula for numerical integration

Description

Numerical integration via trapezoidal formula.

Usage

trapzc(step, f)

Value

int

The value of integral computed numerically by trapezoidal formula.

Arguments

step

step of the grid

f

grid evaluation of density

Examples

Run this code
# Example (zero-integral of fcenLR density)
t = seq(-4.7,4.7, length = 1000)
t_step = diff(t[1:2])
mean = 0; sd = 1.5
f = dnorm(t, mean, sd)
f.fcenLR = fcenLR(t,t_step,f)
trapzc(t_step,f.fcenLR)
