EW_Fi_MLM_func: Function to generate the Expectation of fisher information at one design point xi for multinomial logit models

Description

Function to generate the Expectation of fisher information at one design point xi for multinomial logit models

Usage

EW_Fi_MLM_func(X_x, bvec_matrix, link = "continuation")

Value

F_x Fisher information matrix at x_i

EU_x U matrix for calculation the Expectation of Fisher information matrix at x_i

Arguments

X_x

model matrix for a specific design point x_i, X_x=h.func(xi)

bvec_matrix

the matrix of the bootstrap parameter values of beta

link

multinomial logit model link function name "baseline", "cumulative", "adjacent", or"continuation", default to be "continuation"

Examples

link.temp = "continuation"
xi.temp=c(80)
hfunc.temp = function(y){
matrix(data=c(1,y,y*y,0,0,0,0,0,1,y,0,0,0,0,0), nrow=3, ncol=5, byrow=TRUE)
}
X_xtemp=hfunc.temp(xi.temp)
