Annexe 17 : Résultat du modèle à effets aleatoires de g sur capbours

En ASE.

RE GLS regression with AR(1) disturbances Number of obs = 92

Group variable: ident Number of groups = 4

R-sq: within = 0.1229 Obs per group: min = 23

between = 0.5330 avg = 23.0

overall = 0.2073 max = 23

Wald chi2(6) = 12.97

corr(u_i, Xb) = 0 (assumed) Prob > chi2 = 0.0435

b = consistent under Ho and Ha; obtained from xtregar

B = inconsistent under Ha, efficient under Ho; obtained from xtregar

Test: Ho: difference in coefficients not

chi2(5) = (b-B)'[(V_b-V_B)^(-1)](b-B)

= -12.30 chi2<0 ==> model fitted on these

data fails to meet the asymptotic

assumptions of the Hausman test;

see suest for a generalized test
