Predictive Analytics in Campaign Management

"Algorithms.io looks nice"
Jozo Kovac replied to KSK's discussion CLTV Model using SPSS Modeler??
"Hi Hema,
it's a bit trickier in banking. There are more products, all with different value and life cycle.
This approach could work:
1. Define products in scope
2. Ask about data for all products preferably on customer level.
3. Data…"
Jozo Kovac replied to m n's discussion How to develop churn prediction model for telecom company?
"Great start!
When you have this dataset then open your favorite DM tool (for example Orange http://orange.biolab.si), import data and train for example decision tree.
You can simply predict what customer will churn in next 3…"
Jozo Kovac replied to KSK's discussion CLTV Model using SPSS Modeler??
"Hi,
let me show one basic approach based on churn rate.
Lets have data at least for 2 years.
Average yearly churn rate = percentage of active customers from year 1 who were active in year 2.
If you know that you loose 10% customers yearly -…"
Jozo Kovac commented on Sandeep Kumar Srivastava's blog post Logistics regression-ROC curve
"Shape is important. You care about how "bads" are distributed. It helps you to:
- Verify if you have enough degrees of freedom
- Expain how good your model catches "bads" on both ends of curve
- Choose right cut-off
-…"
Jozo Kovac replied to Sharath Dandamudi's discussion Computation of Weight of Evidence when either the number of bads or goods in a class of a variable is 0
"Exactly as you've written - it's undefined for some categories.
Such categories can't be used by logistic regression as well.
You have several options:
- discard attributes having such categories
- merge categories so none of them…"
Jozo Kovac replied to Sharath Dandamudi's discussion Pros and cons of Dummy variable vs WoE approach for variables in Model building
"I understand well. It's about terminology.
WoE=Weight of Evidence is metrics and has own formula.
Dummy variable is binary flag created from categorical variable with more than 2 categories.
And again - simpler model is better. If…"
Jozo Kovac replied to Sharath Dandamudi's discussion Pros and cons of Dummy variable vs WoE approach for variables in Model building
"First - you can compute WoE for both dummy and categorical variable, they aren't competitors.
Second - dummies lower degrees of freedom, produce simpler models and simpler is better according Occam's razor. And maybe also less sensitive to…"
Jozo Kovac commented on Vincent Granville's blog post Identifying the number of clusters: finally a solution
"Nice idea.
# of clusters unveiled. Good you still keep method for selection of right clustering dimensions for yourself.
Otherwise everything would be automated and consultants may only start-up their hot-dog business. "
Jozo Kovac commented on Vincent Granville's blog post Two great ideas to create a much better search engine
"To protect your webpage from unwanted traffic you may just disable Alexa, Quantcast, etc. code for bad visits.
So visitor can see his content and measurement tools aren't affected (display measure code only for good visits).
If you block a…"
Jozo Kovac commented on Vincent Granville's blog post Two great ideas to create a much better search engine
"Vincent, can't you write set of rules what would handle a traffic from unwanted sources?
e.g. IF HTTP_REFERRER like "%google.in%q=%career%' THEN dont_count_a_visit

Jozo Kovac replied to DEVANAND's discussion Improving the existing predictive model
"How have you built your model last year? Can't be the same methodology repeated on new data?"
