Factor analysis r practice (with R installation tutorial and code)

The steps of factor analysis ：

Step1: Determine the number of factors to extract

Step2: Choose a factor extraction method and a rotation method

Step3: Factor analysis R Practice and visualization

Step2: Factor extraction and rotation

Both factor extraction and rotation methods have many kinds and involve complex mathematical principles , So this article only briefly introduces some commonly used methods .

Factor extraction （factoring method）： Algorithm for calculating factors . Each method uses different mathematical principles to try to find the most different in the database factor (factor). Common methods are as follows ：
