  • Errors when regressing System GMM

    Hello all Statalists,
    I'm new to Stata and I'm learning to use it to do my thesis. Gradually, I find it's actually interesting and helpful to use Stata for regression. However, because I'm jusst a starter so I'm always confused with new type of code. Currently, I'm trying my best to regress GMM model using xtabond2 but each time I run my code it always has errors as follow:

    xtabond2 cash l.cash mb size cf nwc capex lev vol rd div i.year i.sector, gmm(l.cash,lag(3 5)) iv (i.year i.sector, eq(level))

    Then I receive this result:

    unknown egen function max()
    stata(): 3598 Stata returned error
    xtabond2_mata(): - function returned error
    <istmt>: - function returned error


    I am a new Stata user, so please forgive me if I have made any foolish mistakes and feel free to let me know. This is very important and urgent issue that I have to find solution myself. Please help me complete my thesis.

    Thank you in advance! I do really hope to hearing from you soon!
