mse {DELTD} R Documentation

## Calculate Mean Squared Error( MSE) by using different Kernels

### Description

This function calculates the mean squared error (MSE) by using user specified kernel. But distribution of vector should be Exponential, Gamma or Weibull. Any other choice of distribution will result NaN.

### Usage

mse(kernel, type)


### Arguments

 kernel type of kernel which is to be used type mention distribution of vector.If exponential distribution then use "Exp". If use gamma distribution then use "Gamma".If Weibull distribution then use "Weibull".

### Value

Mean Squared Error (MSE)

### Examples

y <- rexp(100, 1)
xx <- seq(min(y) + 0.05, max(y), length = 500)
h <- 2
gr <- Gamma(x = xx, y = y, k = 200, h = h)
mse(kernel = gr, type = "Exp")
## if distribution is other than mentioned \code{type} is used then NaN will be produced.
## Not run:
mse(kernel = gr, type ="Beta")

## End(Not run)
