Problem 1. An observation is made on a vector X of random variables X, 1' = 1, . . . n. The goal is to estimate a
parameter 9 on which these variables depend. Specically, it is known that the dependence is linear, i.e. that the
following model holds: X =
function [stuvec,avevec]=rolodex(calltries,stunum)
stuvec = 1:stunum;
termvec = zeros(1,calltries);
avevec = zeros(1,stunum);
brterm=zeros(1,calltries);
srterm=zeros(1,calltries);
for n=1:stunum;
a = zeros(1,n);
d = zeros(1,n);
termvec = zeros(1,n);
for r
