Peter 3 4 n/a
Magnus n/a 2 5

14. Slope one

Frida 5 3 2
Peter 3 4 n/a
Magnus n/a 2 5
Magnus(Dress|Sweater)=2+[(5-3)+(3-4)]/2=2.5

15. Slope one
Dress Sweater Pants
Frida 5 3 2
Peter 3 4 n/a
Magnus n/a 2 5
Magnus(Dress|Sweater)=2+[(5-3)+(3-4)]/2=2.5
Magnus(Dress|Pants)=5+(5-2)=8

16. Slope one
Dress Sweater Pants
Frida 5 3 2
Peter 3 4 n/a
Magnus n/a 2 5
Magnus(Dress|Sweater)=2+[(5-3)+(3-4)]/2=2.5
Magnus(Dress|Pants)=5+(5-2)=8
Magnus(Dress)=[2*M(D|S)+M(D|P)]/(2+1)=4.33

Piece of cake!
$(‘#search’).click( function() {
$(‘#results ul’).load(‘search?q=’+$(‘#search’).text,
function() { $(‘#results’).animate(
{‘height’: ‘300px’},150)
})})
