Notes: Chow test for 1984 model transferability:

Ess1 = error sum of squares of Haifa set

Ess2 = error sum of squares of Tel Aviv set

Ess3 = error sum of squares of combined set

K = number of parameters in the model including the constant

Ni = number of observations in model i

H0: β1i = β2i   ∀i

H1 = else α = 0.05
uppercase e lowercase s lowercase s subscript {3} minus (upperrcase e lowercase s lowercase s subscript {1} plus upperrcase e lowercase s lowercase s subscript {2}) divided by uppercase k dot (uppercase n subscript {1) plus uppercase n subscript {2} minus 2 dot uppercase k) divided by (upperrcase e lowercase s lowercase s subscript {1} plus upperrcase e lowercase s lowercase s subscript {2}) = (20124 minus (9351 plus 10505)) divided by 12 dot (3243 dot 4356 minus 2 dot 3) divided by (9351 plus 10505) = 7 point 86
uppercase f subscript {(lowercase k, uppercase n subscript {1} plus uppercase n subscript {2} minus 2 dot uppercase k} = uppercase f subscript {(13, infinity}) = 1 point 72 right hand arrow uppercase h
