Examples

##---- Should be DIRECTLY executable !! ----
##-- ==>  Define data, use random,
##--	or do  help(data=index)  for the standard data sets.

## The function is currently defined as
function (x_len, x_mean, x_var, y_len, y_mean, y_var, y) 
{
    x_dof = x_len - 1
    y_dof = y_len - 1
    alpha = 1 - y
    tval = qt(alpha, x_dof + y_dof)
    mgd_var = (x_dof * x_var + y_dof * y_var)/(x_dof + y_dof)
    lower = (x_mean - y_mean) - tval * (x_dof + y_dof) * sqrt(mgd_var * 
        ((1/x_len) + (1/y_len)))
    upper = (x_mean - y_mean) + tval * (x_dof + y_dof) * sqrt(mgd_var * 
        ((1/x_len) + (1/y_len)))
    c(x_dof, y_dof, alpha, tval, mgd_var)
  }
