Estimation of value at risk (VaR) index of mobarakeh steel company using two-sided lomax GARCH model [PDF]

open access: yesتصمیم گیری و تحقیق در عملیات, 2022
Purpose: We have introduced the two-sided Lomax-GARCH (TSLx-GARCH) model. We have used this model to create a more realistic value-at-risk value index than other distributions for all confidence levels. We find this index for applied data.Methodology: In
