資產負債管理之研究分析
為了解決python var 的問題,作者宣葳 這樣論述:
本研究由三篇關於保險業資產負債管理議題的論文所構成。本文第二章檢視在台灣地區銷售之典型利率變動型壽險之公平定價問題。假設資產過程滿足Heston隨機變動模型、利率過程為CIR 模型,保險給付將為一系列遠期起點期權之總和。本文就台灣財務市場之資料進行模型參數估計,再利用蒙地卡羅法計算契約公平價格,同時計算風險值(VaR, ES)。本文第三章闡述國際板債券評價系統的實作細節。台灣保險業總資產近兩成之國際板債券在IFRS-9 會計準則下非為純債務工具,必須以公允價值衡量。在此我們敘述以美國固定期限公債收益率或美元LIBOR及ICE利率交換率校正的利率期限結構,配合芝加哥期貨交易所的歐式利率交換選擇
權隱含波動度資料估計Hull-White 短期利率模型之評價理論細節,並使用開放原始碼程式語言Python 與函式庫QuantLib 及三元樹演算法實作國際板債券評價系統。除與櫃買中心系統價格輸出結果相比較外,我們展示本系統在給定利率期限結構與市場現有商品規格下可贖回債券期初價值與隱含年利率、不可贖回期間與可贖回頻率關係之計算。本文第四章探討copula-GARCH 模型在變額年金保證價值計算上的應用。有效的風險管理前提在於推估各種資產間的機率關係,並計算反映系統狀態的各種定量指標的能力。現代計算技術的進步使得更符合實際、不須過份簡化的多變量機率模型運用變為可能,而copula 正是如此的多變
量機率模型。結合GARCH 時間序列模型,我們利用一系列基於無母數統計與經驗過程理論的穩健統計檢定方法,針對給定S&P500 與S&P600 指數時間序列選擇並匹配最適copula-GARCH 模型,進而推估變額年金保證價值。

使用機器學習進行時間序列分析:從工業廢水中去除重金屬的案例研究
為了解決python var 的問題,作者亞瑟瑪 這樣論述:
使用機器學習進行時間序列分析:從工業廢水中去除重金屬的案例研究學生:亞瑟瑪 指導教授:黃晧元 智 大 學工業工程與管理學系(所)摘 要 在這項研究中,提出了一種時間序列分析法來預測工業廢水中的重金屬濃度。預測使用了長短期記憶(LSTM)和自迴歸綜合移動平均 (ARIMA) 模型完成的,並輔以對 ARIMA 和 LSTM的超參數優化。工業廢水資料中以pH值、重金屬濃度、化學A和化學B量、氧化還原電位、電導率為輸入,重金屬濃度為輸出。本研究首先進行探索性數據分析,並進行政規畫以改進模型學習。 LSTM 和 ARIMA 的超參數使
用網格搜索 (Grid search) 和粒子群最佳化 (PSO)進行了調整。發現 PSO 有效地搜索神經網絡的超參數並提供最佳超參數。性能指標基於統計值進行評估,包括均方誤差 (MSE)、平均絕對誤差 (MAE),並開發了均方對數誤差 (MLSE) 來研究模型評估。另進行了敏感性分析以找出有影響的參數。最終所提出的模型是一個深度學習模型,可以幫助制定廢水處理的控制計劃。
