comment Why use logistic regression instead of SVM?
Helpful, thanks.

comment Multiple regression - A question about dependent variable
For best learning and to draw the best answers, avoid broad "should I?" and "must I?" questions. Instead, consider what will be the consequences of certain choices, then ask for more info about those consequences if you have specific questions.

Fidgety? Please elaborate.

3-D scatterplot would preserve granularity.

comment adding interaction term gives opposite relation
"How to interpret" questions tend to mean "teach me about this topic." Very broad, and likely covered in previous threads on this site. Suppose you read through them and then see whether you still have a specific question about your situation.

comment Should parsimony really still be the gold standard?
Although you mention forecasting, most of your answer seems to apply only to explanatory modeling.

comment two ways of predicting a categorical variable?
Could you explain how or why the 2nd approach produces better results, or say something about "the advantages and disadvantages of both approaches"?

comment meta-analysis of p values
Isn't this a non-standard and potentially misleading way to conduct meta-analysis? I would expect to see an analysis in terms of effect size.

comment I need to establish performance metrics using data I gathered in a trial period
Try looking up norm-referenced and criterion-referenced assessments. That may give you material with which to ask a more focused question here, if applicable.

comment Several 3-way anova vs one 4-way ANOVA
Please consider: if each variable, A, B, and C, had just 2 levels, then there would be 2x2x2=8 groups. Does this design really have only 3? And if so, what splits the participants into these 3? I suspect that where you speak of "variables" you actually have 3 levels of a single variable.

comment Is there a way to test whether or not you're “over-controlling?”
Very worthwhile line of questioning to pursue. Please check out the threads on this site tagged with 'variable selection,' 'multicollinearity,' and (if you haven't already) 'regression' and 'control.'

comment Useful plots for plotting the errors of a multinomial logistic regression model?
Thanks for the code but I was actually referring to your display itself :-) Might help people give you better comments about your analysis.
