Multiple Factor Analysis by Example Using R''An introduction to exploratory techniques for multivariate data analysis, this book covers the key methodology, including principal components analysis, correspondence analysis, mixed models and multiple factor analysis. The authors take a practical approach, ...
Valentin: Multiple Factor Analysis describe the six wines. For each wine, the expert rated the inten- sity of the variables on a 9-point scale. The results are presented in Table 1 (the same example is used in the entry for STATIS). The goal of the analysis is twofold. First we want...
You can carry out multiple regression using code or Stata's graphical user interface (GUI). After you have carried out your analysis, we show you how to interpret your results. First, choose whether you want to use code or Stata's graphical user interface (GUI)....
Each of its sensory properties, such as appearance, odour, texture and flavour, is assessed using several descriptors that are then quantitatively measured using an appropriate scale. [7] Multiple factor analysis (MFA) is an alternative to principal component analysis (PCA)[15] allowing to balance...
Combine multiple ggplots using ggarrange() Create some basic plots # 0. Define custom color palette and prepare the datamy3cols <- c("#E7B800","#2E9FDF","#FC4E07") ToothGrowth$dose <- as.factor(ToothGrowth$dose)# 1. Create a box plot (bp)p <- ggplot(ToothGrowth, aes(x = dose...
A 2x2 pooling layer with a stride of two reduces the height and width of the image by a factor of 2. In such a pooling layer a 2x2 neighborhood of a pixel is compressed to a single pixel. Different types of pooling performs the compression in different ways. Max-pooling considers the...
R code for Post hoc analysis for the Friedman’s Test The analysis will be performed using the function (I wrote) called “friedman.test.with.post.hoc”, based on the packages “coin” and “multcomp”. Just a few words about it’s arguments: ...
The Multiple Factor Model can be used to decompose returns and calculate risk. Following are some examples of the Multiple Factor Models: The expected returns factor model: Commonality In The Determinants Of Expected Stock Returns by R. Haugen, N. Baker

Multiple linear regression is used to determine how different factors affect something you want to predict. For example, you're trying to figure out how much an oil stock will be priced at. Rather than looking at just one factor, like the overall market, MLR considers many factors at once,...
