[R] Solve an Equation Including Integral

[Steven Stoline]

Dear All: I submitted this post to the R-sig-Teaching List too


I am trying to solve an equation including an integral for unknown
parameter.


Is this can be done in R? if so, any helps will be highly appreciated



### The following function is a function of t, given exi, nu, and alpha.


fun<-function(exi,nu,alpha)
(nu+t^2)^(-(nu+1)/2)*exp(((nu+1)*exi*t)/((nu+t^2)^0.5))


### I want to solve "[Integral(-Inf,100) fun(exi,nu,alpha)]-(1-alpha)=0"
for t.

### That is, find the value of t which satisfy the equation:

             [Integral(-Inf,100) fun(exi,nu,alpha)]-(1-alpha)=0


### for example given: alpha = 0.05, nu = 20 , exi = 0.5, Solve for t.


with many thanks
steve
