Standardised items tend to be skewed; box and whiskers can look like scrambled eggs. Thanks for the information. I have both positive and negative loadings. Kindly guide me on how i should interpret the data.
Your piece about the axes being small than 90 degrees makes perfect sense! Thank you! Your email address will not be published. Skip to primary navigation Skip to main content Skip to primary sidebar by Maike Rahn, PhD Rotations An important feature of factor analysis is that the axes of the factors can be rotated within the multidimensional variable space. Here is a visual of what happens during a rotation when you only have two dimensions x- and y-axis : The original x- and y-axes are in black.
Instead, we get this result: Variables Factor 1 Factor 2 Income 0. What happened? Here is a display of the oblique rotation of the axes for our new example, in which the factors are correlated with each other: Clearly, the angle between the two factors is now smaller than 90 degrees, meaning the factors are now correlated.
Comments Clear explanation. Thank you. Very informative and nicely explained. Best Regards,. But I only need to perform the varimax rotation Please provide the help. Very good explanation…this way concepts are very clear..
Very clear and useful description, also understandable for non-mathematicians, e. Leave a Reply Cancel reply Your email address will not be published.

Orthogonal versus oblique factor rotation: A review of the literature regarding the pros and cons. Warner, R. Applied statistics: From bivariate through multivariate techniques 2nd ed.

For example, when you take a multiple choice Introductory Psychology test, a factor analysis can be done to see what types of questions you did best on and worst on maybe they did best on factual types of questions but really poorly on conceptual types of questions.
Factors are taken from a data set and then rotation of the different factors typically occurs. Rotation methods simplify factors and make results more reliable and easier to interpret.
