    Published 2024-09-01
    “…The unique feature of this method is that it introduces a penalty term in the minimization to address the computational problem of a set of parameters; The parameters are calculated as follows: min(α.β)Σk=1KΣt=1TΣi=1N wkρτkyit-αi-xitTβτk+λΣiNαi                              (6) In equation (6), i represents the number of countries (N), T represents the index for the number of observations of each country, K represents the quantile index, x is the matrix of explanatory variables, and ρτk is the quantile loss function. Also, Wk represents the relative weight for the kth quantile. λ is an adjustment parameter that reduces individual effects to zero to improve the performance of β estimates. …”
