<div class="moz-cite-prefix"> I was also interested in Biber's
multidimensional analysis, and tried to replicate it. But just
when I began looking at the implementation of it, a problem
confronted me.<br>
<br>
The idea behind multidimensional analysis was that we have an
intuition that linguistic variables pattern differently in
different registers and genres, but the pattern is rarely simple
enough to say "Genre 1 has x, y and z values, but Genre 2 has x, a
and b values." Biber basically threw all the variables in a pot
and shook it to see which ones patterned together. Those factors
were labeled as the dimensions of variation.<br>
<br>
The problem is that variables don't just pattern together for
reasons of register and genre. Sometimes they pattern together
for grammatical reasons; for example, his Dimension 1 is
essentially frequent noun morphology vs. frequent verb morphology,
and thus could simply be explained by the relative frequencies of
nouns vs. verbs in the text.<br>
<br>
I had an idea that this could be overcome by bringing the
notion of the "envelope of variation" over from variation theory,
and I mentioned it to Biber. He was interested, but my study did
not support the idea. If anyone else can think of a way to
overcome this obstacle, I'd be interested to know it.<br>
<br>
I discussed this in greater detail in my 2006 paper; if anyone
wants to read it but doesn't have access, please let me know.<br>

Tagger</a> is very useful which has tagged my corpus with
those 67 features and has calculated their score in each text.
Since it does not perform Factor Analysis, I have provided
myself with SPSS 17. As I am a beginner in MD Analysis, and
have least idea about using SPSS, I am requesting here for
assistance. I have tried to perform Factor Analysis in SPSS by
following steps provided in online tutorials. But as a result
SPSS output window doesn't show anything under Factor Analysis
heading. I had selected Maximum Likelihood Extraction method
and Promax Rotation. Is there a guide/ tutorial available to
select appropriate options in SPSS for MD Analysis?</div>
