【正文】 應(yīng)用詮釋，而不用太多時間花在計量軟件操作的指導(dǎo)。 特別的是，gretl 是一個完全免費(fèi)的自由軟件，大家可以自由下載，在教學(xué)上或使用上，都十分方便，并且可以理直氣壯。 gretl 雖然源自于 Linux 操作系統(tǒng), 但它的 Windows 版本 也十分好用, 特別是初學(xué)者幾乎不需學(xué)習(xí)任何語言指令, 只要用點(diǎn)選選單、填入數(shù)據(jù)的方式，就可以估計大部份的統(tǒng)計檢定和計量模型，功能十分完整，繪圖部份則由著名的 gnuplot 來支持顯示，其多樣性不在話下，相較于其它有名的商業(yè)收費(fèi)統(tǒng)計軟件而言，一點(diǎn)也不遜色。Gretl 入門手冊for 中文版 gretl Gnu Regression, Econometrics and Timeseries 楊奕農(nóng)中原大學(xué)國際貿(mào)易學(xué)系 Chung Yuan Christian University, Taiwan. current ver.
