This article shows how to use Excel to perform multiple regression analysis. Unfortunately, based on the brief description that you have given, I don’t understand the problem that you are trying to solve or how factor analysis can be used. Wasn’t sure how, until I came across this page. I have described how to deal with categorical variables in the context of regression, but I don’t know how much sense this will have in the context of factor analysis. Charles. Multiple Factor Analysis (MFA) makes it possible to analyze several tables of variables simultaneously, and to obtain results, in particular, charts, that allow studying the relationship between the observations, the variables, and tables (Escofier and Pagès, 1984). Click here for a complete description of this example. You can use factor analysis to determine what are these concepts (i.e. Problem arises when a multiple regression model is involved. Can you show me in excel how I can create factor loadings for country and sector indices via PCA, MLE and Regression please. Factor Regression Analysis. Dr Charles! The wikiHow Tech Team also followed the article's instructions and verified that they work. 7 0.777281588 0.777281588 0.540061725 Charles, am very grateful. If the value of Cronbach’s alpha is -46.8 then you probably made an error in the calculation. My guess is that you can continue with the analysis.

Question with factor analysis. k 57 Multi-factor analysis of variance (ANOVA) is used to test the null hypothesis that each effect's level means are all equal, simultaneously for each of multiple factors/effects. The ‘With Replication’ is when the participants do more than one sample. 52 Respondents have given responses for 57 factors This method demonstrates the influence of two factors on the variance of a random variable's value. In our case, there 6 persons and each take three (>1) dosages. For example: Very open ended with some surveys being actual interviews. Charles. Exploratory factor analysis (or EFA) is a method that reveals the possible existence of underlying factors which give an overview of the information contained in a very large number of measured variables. I am sorry, but I don’t completely understand the issue that you are describing. Charles, How to use factor analysis for “Project on effectiveness of Recruitment Process Outsourcing at safeducate”, Vedant, Charles. This course is part of the iMBA offered by the University of Illinois, a flexible, fully-accredited online MBA at an incredibly competitive price. The Real Statistics website shows how to do this. Do you have some specific questions about the process? Would these answers be grouped with common words/themes and then numbered to create a factor analysis similar to your example. You may want to consider Cronbach’s alpha. wikiHow is a “wiki,” similar to Wikipedia, which means that many of our articles are co-written by multiple authors. Let's consider an example of performing the two-factor variance analysis in Excel. I have a data from 44 people for pilot study (23 questions).when i run reliability test (Cronback’s alpha ) the value is 0.856. but when i do the validity test by using principal component method or any other methods it give value as 0.56.. is it a bad score?
