Analyzing Baseball Data With R

為了解決mlb cover的問題，作者Albert, Jim/ Baumer, Benjamin S./ Max, Massimiliano 這樣論述：

Analyzing Baseball Data with R Second Edition introduces R to sabermetricians, baseball enthusiasts, and students interested in exploring the richness of baseball data. It equips you with the necessary skills and software tools to perform all the analysis steps, from importing the data to transformi

ng them into an appropriate format to visualizing the data via graphs to performing a statistical analysis.The authors first present an overview of publicly available baseball datasets and a gentle introduction to the type of data structures and exploratory and data management capabilities of R. The

y also cover the ggplot2 graphics functions and employ a tidyverse-friendly workflow throughout. Much of the book illustrates the use of R through popular sabermetrics topics, including the Pythagorean formula, runs expectancy, catcher framing, career trajectories, simulation of games and seasons, p

atterns of streaky behavior of players, and launch angles and exit velocities. All the datasets and R code used in the text are available online.New to the second edition are a systematic adoption of the tidyverse and incorporation of Statcast player tracking data (made available by Baseball Savant)

. All code from the first edition has been revised according to the principles of the tidyverse. Tidyverse packages, including dplyr, ggplot2, tidyr, purrr, and broom are emphasized throughout the book. Two entirely new chapters are made possible by the availability of Statcast data: one explores th

e notion of catcher framing ability, and the other uses launch angle and exit velocity to estimate the probability of a home run. Through the book's various examples, you will learn about modern sabermetrics and how to conduct your own baseball analyses.Max Marchi is a Baseball Analytics Analyst for

the Cleveland Indians. He was a regular contributor to The Hardball Times and Baseball Prospectus websites and previously consulted for other MLB clubs.Jim Albert is a Distinguished University Professor of statistics at Bowling Green State University.

中華職棒大聯盟打者薪資預測模型之建構

為了解決mlb cover的問題，作者朱柏璁 這樣論述：

球員是職業棒球運動的核心，也是球隊的資產，球員的表現好壞影響到球賽的結果，而以球賽輸贏作為收受電視轉播權利金、販賣球票、促銷商品、招攬贊助、創造營收和品牌延伸主要訴求的球隊來說，球員便是他們的生財工具。台灣職棒(中華職棒大聯盟)過去二十多年來勞資雙方因薪資爭議尋求仲裁的案件約有20件，不僅破壞雙方的形象，更會造成負面結果影響球員場上的表現。因此本研究的目的希望尋求一個客觀且科學的工具和模型，球員得以藉由表現估算合理價值，並藉以作為薪資協商的依據，使其得以專心於可以創造價值的球賽上。球隊也可以減少談薪的心力，而能在其預算範圍內，對球員依照建議模型進行論功行賞的標準。本研究為了使大眾容易使用，先

參考過去文獻，並進行前測篩選出影響中華職棒大聯盟2008至2016年打者薪資的重要參數，並以最容易被解讀且接受的迴歸分析計算出各個薪資影響參數的權重，建立薪資預測模型。再以模型預測之薪水與實際薪水比較去檢測模型準確性，而後將2017及2018年的資料帶入以檢驗模型之預估能力，最後再以前人研究中所提及的相關因子進行三因子的模式建立，並比較與其模型間的準確性。扣除出賽次數過少的球員後，總計納入303名球員之資料進行模型建立，初步模型中分析出有9個因子與薪資有相關性，再依前人研究中與前測結果挑選出年紀、整體攻擊指數及勝利貢獻指數所建構的薪資預測模型，以平均絕對百分比誤差 (MAPE)驗證發現這個模型

具有高度的準確性，且薪資被高估及被低估的人數相仿；不同年間的誤差也都落於高準確度及良好準確度之間，而在所有薪資區間中，模型預測的能力也接近相同。且在預測能力方面，2017及2018兩年的資料都將接近高準確度，且所有的球員的預估薪資都落在合理的預估範圍內，且約半數的球員都落在高準度範圍內。而預估薪資稍微高於實際薪資，表示依據球員的表現，球團應給予球員更高的薪資，這也反映了和往年相比，2017和2018年野手薪資成長率的下降。而為了進一步比較三因子是否足以預估薪資，由相同取樣年間的前人研究中所挑選的十個因子進行120組的模型比較，本研究所挑選的三個因子預估能力準確度仍較高。本研究所得之薪資預測模型

雖並不複雜，但仍保有高準確度，方便使用，此外隨著時間推移準確度改變的幅度很小，因此可供未來參考。由於本研究所得之薪資預測模型，主要考量打者的表現參數，惟諸如明星魅力、球團戰績以及球團預算等變數，建議後續研究仍可加以探討。此外，本研究結果適用對象並不包括投手薪資，故針對投手的薪資預測模型亦仍待後續研究者探討。建議球隊可以建立公平公正與公開的核薪機制，球員也應積極建立自我形象，政府也可以促使專業的運動經紀人發展，以利職業棒球市場蓬勃興旺。

以外顯因素、虛擬社群分析中華職棒觀眾人數

為了解決mlb cover的問題，作者翁培文 這樣論述：

中華職棒是台灣最盛行的職業運動，觀眾的多寡關係到球隊的營收，是職棒能否長久經營的關鍵。國內外有許多與進場觀眾人數相關的研究，影響觀眾人數多寡的因素頗多，有些與時間相關、有些與戰績相關、有些與地理相關，還有許多其它種類的因素。MLB與觀眾人數相關的研究已有一定的成果，中華職棒類似的研究較少，本研究以中華職棒2011-2015年觀眾人數為研究議題，採用約50個自變數，多元迴歸調整後的R2為.768。地理學常以現實世界為研究對象，對新興的網路空間較少著墨，本研究試圖結合棒球與網路空間，探討虛擬社群的人數變化能否應用在棒球經營。使用PTT三個討論板的人氣資料分析觀眾人數時，相關係數較差，但三個自變數

都有達到顯著水準，由於網路空間和現實世界有些許差異，在納入現實世界的幾個因素後，能獲得更佳的成果，這顯示網路資料確實能應用在觀眾人數的分析，值得日後投入更多資源進行研究。
