Factor analysis: The effects of distribution type, number of factors, factor loadings, number of variables per factor and sample size on the rules used to determine the number of factors to retain.The primary goal of factor analysis (FA) is to understand the underlying structure or covariation ...

作因素分析常會碰到因素負荷量 (factor loadings) 與特徵值 (eigenvalues) 這兩個詞,不過在學習因素分析常碰到的問題是:數學太多了。 對於不懂矩陣、數學的人來說,這就像天書一樣。我給自己設定目標就是:不講太多數學而能把這兩個名詞是什麼解釋清楚,並說明有什麼用。
What is Factor Analysis?Factor analysis examines which underlying factors are measured by a (large) number of observed variables. Such “underlying factors” are often variables that are difficult to measure such as IQ, depression or extraversion. For measuring these, we often try to write ...
aThe factor analysis results presented in Table C1 show the factor loadings (that is the correlations between the measures and the factor) and the eigenvalue (representing the amount of variance that is accounted for by the factor). 要素分析结果在表C1展示提出了(是措施和因素之间的交互作用)的因...
因子分析(Factor Analysis)是一种统计方法,用于描述多个观测变量之间的相关性。它能够帮助我们理解一大堆数据中各个变量之间的相互关系。它假设在这些显而易见的观测变量(比如考试成绩、问卷调查结果等)背后,存在一些我们看不见的潜在变量(或者称为“因子”),正是这些因子在暗中操控着观测变量之间的相互关联。因子分析...

Factor Analysis Data Considerations Data.The variables should be quantitative at theintervalorratiolevel. Categorical data (such as religion or country of origin) are not suitable for factor analysis. Data for which Pearson correlation coefficients can sensibly be calculated should be suitable for factor...
