"Mathematics for Econometrics" Hisatoshi Tanaka Price: ¥2600 #HisatoshiTanaka #Hisatoshi_Tanaka #Books #Society/Economics_Finance I've flipped through it after purchasing, and there are pages with highlighted lines. However, I haven't read it since then, and it's been stored on the bookshelf for about two years. Please consider purchasing if you don't mind the highlighting and still find it usable as a reference book.
