  • Getting Breusch-Pagan LM Test p-value as 1

    Dear Forum Fellows

    I would appreciate if you please give me your expert opinion on one of the problem I am facing.
    I have 9 Independent variables, 7 countries, 24 years panel data.
    While using LM test to decide in between OLS or Random effect model, I am getting prob-value 1.0000....signalling to choose OLS WHEREAS I am also getting hausman test prob-value as 0 which signifies that Fixed effect is preferred.....
    In such case, i am not getting what i have done wrong bcoz of which i am getting contrasting result


    Looking for your best comments. appreciate if you please explain how I should I proceed further.

    These are test results
    xttest0
    Breusch and Pagan Lagrangian multiplier test for random effects
    fdii[countrycode,t] = Xb + u[countrycode] + e[countrycode,t]
    Estimated results:
    | Var sd = sqrt(Var)
    ---------+-----------------------------
    fdii | 1.981186 1.407546
    e | .7544939 .8686161
    u | 0 0
    Test: Var(u) = 0
    chibar2(01) = 0.00
    Prob > chibar2 = 1.0000

    Hausman (1978) specification test
    Coef.
    Chi-square test value -14.503
    P-value 1
    AFTER SIGMAMORE CORRECTION
    Hausman (1978) specification test
    Coef.
    Chi-square test value 74.084
    P-value 0
