The World Atlas of Language Structures (WALS) is a database of structural (phonological, grammatical, lexical) properties of languages gathered from descriptive materials. [1] It was first published by Oxford University Press as a book with CD-ROM in 2005, and was released as the second edition on the Internet in April 2008.

Wald用于对B值进行检验，考察B值是否等于0。 若B值等于0，其对应的OR【Exp (B)】为1，表明两组没有显著差异。 OR等于B值的反 自然对数。 Wald值越大，B值越不可能等于0。 S.E.是标准误,表示估计值的平均误差.wals是一个统计量,用检验 自变量 对因变量是否有影响的.它越大,或者说它对应的sig越小,则影响越显著.df是 自由度,在分析中不用解释. 实践应用中,关键的是解释系数B,或者后面的Exp (B),称为OR.还有sig,其它的可以不管. SPSS表中的B值，OR值、Wald值各自代 …

A feature is a structural property of language that describes one aspect of cross-linguistic diversity. A WALS feature has between 2 and 28 different values, shown by different colours on the maps. Most features correspond straightforwardly to chapters, but some chapters are about multiple features.

Jun 28, 2024 · y帽表示优化这个回归方程，y也是预测的概率，使用y帽这个函数是为了使最后的值范围在0~1之间; L是损失函数，他表示我们的预测值与真实值的接近程度，作用类似于方差; 我们就是利用反向推到求出w，b

Currently WALS is providing resources to ALS clinics throughout North America including consensus clinical management papers. We strive to connect ALS healthcare providers across different clinics and different focuses.
