Dear friends:

     I am a new R user, and not very good at statistics and maths
     I find it difficult to find the minimum of this item:

    It seems that the method optim can find the minimum. I tried several times , but R constanly tells that " failure to find b or p"

    Would you please give some suggestions?     Thanks in advance.
    Best wishes,
    Bin Yue
