NEW FEATURES:
Real-world questions and data—the effect of reductions in class size on test scores and the returns to education—create a continuous platform that motivates important theoretical ideas, and link student understanding to real-world empirical applications.

Contemporary theory and practice are reflected in the choice of topics, focusing on the procedures and tests commonly used in modern practice.

An opening review of statistics and probability emphasizes sampling variability, sampling distributions, and how sampling uncertainty is handled using the methods of statistical inference.

Treatment of Multiple Regression focuses not only on mechanics and tools, but also on how those tools are useful because they address omitted variable bias.

By allowing for heteroskedasticity from the outset, students have an easier time understanding the method and instructors are able to apply the theory earlier in the course.

Core regression material in Part II is presented in four, carefully developed chapters:
Chapter 4, Linear Regression with One Regressor, focuses solely on Ordinary Least Squares (OLS) estimation and assumptions.

Chapter 5, Regression with a Single Regressor: Hypothesis Tests and Confidence Intervals, focuses on inference using OLS, including an expanded discussion of heteroskedasticity and homoskedasticity, a discussion of the t-distribution, and an expanded discussion of motivation for using OLS.

Chapter 6, Linear Regression with Multiple Regressors, includes an

南方澳鯖魚文化季鯖魚踩街遊行。(資料照,讀者李忠衛提供)

[記者簡惠茹/宜蘭報導]今年南方澳鯖魚文化季終於不燒魚,往年長達7公尺、超過百公斤的大鯖魚模型踩街後就會焚化,引起許多民眾覺得可惜又不祥,議員邱嘉進也不斷請命留下活口。討海文化保育協會表示,精美的模型將保留在遊客中心,讓更多遊客欣賞。

去年開始宜蘭縣南方澳鯖魚節與鯖魚祭兩個活動合辦,由宜蘭縣政府舉行「南方澳鯖魚文化季」,而原本鯖魚祭中的燒鯖魚祈福儀式原本也保留下來,宜蘭縣討海文化保育協會每年都會製作長達7公尺、重達160公斤的大鯖魚模型,搭船巡港祈求平安,之後會沿街由10名壯漢扛著大鯖魚到內埤焚化,象徵敬拜海洋之母。

但是往年製作鯖魚模型繞港祈福,最後到內埤海灣焚燒,常遭在地人士和漁民質疑不祥,議員邱嘉進這幾年來也不斷為模型請命,他說,希望保留鯖魚作為展示之用,鯖魚模型一條成本都很高,如果只是做來燒掉很可惜,應該賦予模型更多觀光價值,同時搭配展覽,讓更多遊客了解南方澳的鯖魚文化。

討海文化保育協會總幹事潘佑升表示,經過許多在地民眾反應後,今年決定不燒魚,會留在南方澳遊客中心展示,本來因為馬上會燒掉,所以是以竹條製作架構,今年預計會以鏢旗魚的鏢杆作為主架構,製作堅固的內裝,外表也會做得更加精美,希望加上燈光,讓鯖魚晚上也能出門發光踩街。

今年兩活動將繼續由宜蘭縣政府合併辦理,宜蘭縣政府漁管所表示,今年預計在10月初辦理,活動包含鯖魚儀式、踩街與社區輕旅行,邀請社區和漁業團體參與,活動中更要進行漁業資源保育宣導與鯖魚推廣的行銷活動,去年鯖魚文化季的經費由漁業署提供100萬元經費,縣府配合款10萬元,今年因為鯖魚模型決定不燒,除了漁業署的經費,縣府配合款會提高到40萬元左右,一方面讓模型做得更加精美,另一方面也讓活動辦理更豐富。
