Predict

Does PredictIQ have the ability to prune trees within models to avoid over fitting. I found this article which talks about this. http://www.statmethods.net/advstats/cart.html

User question received today. "When I’m running various iterations of a model (let’s saying Categorical Binning Yes/No and Numeric Binning Yes/No) there are 4 iterations. However, I can’t analyze each...

What settings have the most impact on run times? I have already seen that if I cap the number of predictors from the default of 50 to 12 this has a big impact. I would assume looking for higher order ...

LityxIQ may still do binning in some situations depending on other settings like choosing to have numeric missing replaced with categories or having too many unique values in a field. It will bin for ...

XGBoost is great, but there may be concern that it results in models that are too good and overfitted. Are there ways to reduce the "tightness" of the model? In the estimation of the predictor coeffic...

Within the PredictIQ model build settings the last tab called output allows you to ‘set population average for target’. This results in the predicted scores being scaled down to reflect the population...

Building a revenue model and I see that Lift 1 over random =3.2 so decile 1 is 3.2 higher than the random. However, Numeric 1 vs 10 is only 2.83 -- what is numeric 1 vs 10 -- would expect it to be dec...

Is there a way that I can tell how long a model run took?

If you took all responders and 1/3 of non-responders, I would historically build models using the Weight statement since not including it would affect the model calibration. In addition, the performan...

Can I output the scoring code for a model I create in LityxIQ?
