Examples

y <- rexp(100, 1)
h <- 0.79 * IQR(y) * length(y) ^ (-1/5)
xx <- seq(min(y) + 0.05, max(y), length = 100)
den <- Laplace(x = xx, y = y, k = 100, h = h)
plot(den, type = "l")


##other details can also be added
y <- rexp(100, 1)
h <- 0.79 * IQR(y) * length(y) ^ (-1/5)
den <- Laplace(x = xx, y = y, k = 100, h = h)
plot(den, type = "s", ylab = "Density Function", lty = 1, xlab = "Time")

## To add true density along with estimated
d1 <- density(y, bw = h)
lines(d1, type = "p", col = "red")
legend("topright", c("Real Density", "Density by RIG Kernel"),
col = c("red", "black"), lty = c(1, 2))
