还是老老实实把操作手册仔仔细细读一遍为上。 正如指南所言“ Remember your first statistics class when you sweated through memorizing formulas and laboriously calculating answers with pencil and paper? The professor had you do this so that you would understand some basic statistical concepts. Later, you discovered that a calculator or software program could do all of these calculations in a split second. This tutorial is a little like that early statistics class.。。。。。”作者: mischina 时间: 2011-7-2 10:18
