If you want to forecast the yield on a $1-$year security in one year from now, you need to build the following equation:

$q,=q,-$ And the yield on $1-$year security in one year would be $$

If you want to forecast the yield on a $1-$year security two years from now, you need to build the following equation:

$q,=.$ And the yield on $1-$year security in two years would be $$

If you want to forecast the yield on a $2-$year security one year from now, you need to build the following equation:

$q,=q,.$ And the yield on $2-$year security in one year would be $$

If you want to forecast the yield on a $3-$year security one year from now, you need to build the following equation:

$v=q,.$ And the yield on $3-$year security in one year would be
