evalFunctionOnParameterDef: Test Whether a parameterDef Ojbect Work Properly for a dgp.

In ezsim: provide an easy to use framework to conduct simulation

Description

several set of parameters is generated from parameterDef. Function fun is evaulated under the index-th set of parameters and returns its value.

Usage

evalFunctionOnParameterDef(x, fun, index = 1, ...)

Arguments

x	A parameterDef object
fun	A function to be evaluated.
index	Which set of parameters to use.
...	unused

Examples

par_def<-createParDef()
par_def<-setSelection(par_def,mean=1,sd=2,n=seq(10,50,10))

evalFunctionOnParameterDef(par_def, function() rnorm(n,mean,sd) )  # 10 random number
evalFunctionOnParameterDef(par_def, function() rnorm(n,mean,sd), index=3)  # 30 random number

## Example 2
par_def <-createParDef()
par_def <- setBanker(par_def,xs=1,b=1)
par_def <- setSelection(par_def,n=seq(20,100,20),es=c(1,10))

dgp<-function(){
x<-rnorm(n,0,xs)
e<-rnorm(n,0,es)
y<-b * x + e
data.frame(y,x)
}
estimator<-function(d){
r<-summary(lm(y~x-1,data=d))
c(b=r$coef[,1],t=(r$coef[,1]-1)/r$coef[,2] )
}

true<-function(){
c(b,(b-1)/(es/sqrt(n)/xs))
}
evalFunctionOnParameterDef(par_def,dgp)
estimator(evalFunctionOnParameterDef(par_def,dgp))
evalFunctionOnParameterDef(par_def,true)
