Visualization for Categorical DV and Continuous IVs

3J LEMA
Can you suggest a graphical presentation for  a Categorical DV and 4 Continuous IVs.

Thank you.

Dear Lema

 

Questions like yours are best answered with the rationale and case scenario(s) already fully explained.

 

Best wishes
Margaret

Re: Visualization for Categorical DV and Continuous IVs

To elaborate on the previous good advice:
What are the variable names?
For the categorical variable, what are the value labels?

What questions do the visualizations address?

For whom are you producing the visualization? Just checking for potential
data entry error? Formal presentation in court of law, etc.

"categorical" can refer to coarsened continuous variables, nominal level
variables, ranks, etc.

What constitutes a case?

How many cases do you have?

*And so forth.*

Speaking abstractly -- meaning, perhaps, special software -- you
may represent continuous numbers with light/dark and rainbow
colors, for two dimensions.  Are you plotting points? or functions?

Assuming you are plotting data points rather than a function, you
may use length and width of an object for two more, though these
are often combined as "size".   The complex shape of the object is
very often used for categories (circle, square, star, ...).  Of course,
this is less usable for hundreds of points than for dozens.

X and Y are the usual axis labels for two continuous variables, and
Z is sometimes represented effectively, one way or another.

It really depends on what you want to show, but one possibility would be to fit a multinomial regression and then plot the category probabiliities against the regressors or something like emm's,

Re: Visualization for Categorical DV and Continuous IVs

I haven't done the multinomial regression that Jon suggests, but
what I have used when the categories are relevant is the
discriminant function for multiple groups.  It has nice ancillary
statistics and displays.

The plot of category centroids on the first two discriminant factors
shows the group separation, and the factors can be interpreted by
their loadings like a factor analysis.  The "within-group" correlations
are also available.
