Représentations sur les deux premiers axes. Éboulis des valeurs propres. Nuage des variables actives. Nuage des variables supplémentaires. Nuage des individus regroupés en trois classes par HCPC.
Please can any one help me with this? the word " nuage" is again more likely to be a computer term...
It is the sentence that follows 'éboulis des valeurs propres' so maybe the person who gave me the excellent answer yesterday, also has the key to this puzzle?
cloud of active variables??

cluster of active variables
The technique is Hierarchical Clustering on Principal Components. So, "cluster" seems more appropriate. "cloud" does exist but tends to be used more in Geometric analysis.

: Yep. And valeurs propres = eigenvalues.

Cloud of active variables
You are correct, "nuage" is an IT term and it refers to the "cloud". "Active variable" also makes sense to me.

Scatterplot of active variables
According to my IT expert, "scatterplot" refers to marks placed on a graph according to x and y values.

: Comparison of an image search on (a) nuage des variables and (b) scatter plot is convincing

DLyons
: A scatterplot is a "nuage de points". "nuage de variables" is rarely used and IMHO more usually in a Geometric context. (And the comparison of the Google images doesn't provide much evidence for this identification).

rkillings
: Scatterplot is a technique of visual representation or a graph drawn using it. The 'nuage' is a pattern perceived within the scatterplot. The cloud is not the sky./ The scatter (of the data set) is not the scatterplot.

Reference:
Cloud
Clustering occurs within a cloud of data points or "data cloud".
"Proposed approach
Assuming that we have retrieved some clusters, our approach is articulated as
follows (see Fig. 1):
1. Linked Data Selection
. We retrieve information about the data contained
in each cluster from the Linked Data cloud, across several datasets."
"Multivariate statistical methods provide a number of different approaches to solving this ... Hierarchical Cluster Analysis is probably the most common method of analysis ..... we find the line through the “cloud” of data points which minimises the ..."
