Plotting more than two dimensions with correspondence analysis

[axphil]

Hello,
is it possible to plot a third and fourth dimension using correspondence analysis? KH Coder does a great job providing two dimensional plots with correspondence analysis. In my specific case variations are explained to a relevant extent by more than two dimension. To give an example:

 Dimension  Cor ^2 Explained

[1,] 1 0.0122 29.71
[2,] 2 0.0104 25.33
[3,] 3 0.0080 19.52
[4,] 4 0.0053 12.91
[5,] 5 0.0028 6.91
[6,] 6 0.0023 5.62
[1] "iterations: 75"

The first two dimension already explain 55,04 percent of variations. To increase my outcome regarding an explanation of variations it would be helpful to have also the third and fourth dimension plotted. Is it feasible for the KH Coder to plot more dimension than two using correspondence analysis? Of course, space is restricted to three dimension but I wonder whether it is possible to visualize a third and fourth dimension. Or is it possible to implement a download option for a table (i.e., csv) with all numeric values of the profiles?

Best regards
Axel

Hello,

With KH Coder, you can make multiple two-dimensional plots. For example, one plot using dimension 1 and 2, another plot using dimension 1 and 3. You can select dimension in the option screen.

Also, you can save the plot in *.csv format.

Best,

Perfect. I thought one just can interchange dimension 1 and 2.
Many thanks for your quick resond.
Bes wishes,

Dear Koichi,

I tried to save my data from a correspondence analysis into a csv.file as you metioned. Unfortunately, even so I used the "save"-button and than "save as type: .csv" files are saved in the *.pdf format. The same problem appears if I try to save in format *.eps, *.png or *.svg. All turn out as pdf.files.

Best wishes,
Axel

Dear Axel,

Are you on Linux or Mac? Then, please select "csv" and then type not only the filename but also the extension ".csv".

You have to type "filename.csv". You need to enter ".csv" part too.

# Yes, this is stupid. I will see if I can change this Tk behaviour.

Hello,
thank you for your quick respond and advise. All data are now saved in *.csv format.

Regarding your question: I use Mac (version 10.13.6) and KH Coder (version 3.Alpha.14b).
