What is the predictive power of a ZIP code?
As we can see, a PPS score of 0.94 is rather high, so the zip code seems to have a good predictive power towards the city. However, if we calculate the PPS in the opposite direction, we might achieve a PPS of close to 0 because the Decision Tree Classifier is not substantially better than just always predicting the most common zip code.
How is the predictive power score ( PPS ) defined?
We define and open-source the Predictive Power Score (PPS). The PPS is an alternative to the correlation that finds more patterns in your data. It is Friday afternoon and your boss tells you that the data delivery surprisingly arrived early — after only 4 weeks of back and forth. This was the missing piece for your predictive model.
Which is the best predictor of future fund returns?
The expense ratio is the most proven predictor of future fund returns. We find that it is a dependable predictor when we run the data. That’s also what academics, fund companies, and, of course, Jack Bogle, find when they run the data.
Is the expense ratio a predictor of future returns?
If you’ve been following Morningstar’s research for long, you know how important we think expense ratios are to the fund selection equation. The expense ratio is the most proven predictor of future fund returns. We find that it is a dependable predictor when we run the data.

How are standardized scores calculated in SPSS using descriptives?
In SPSS, you can compute standardized scores for numeric variables automatically using the Descriptives procedure. One important distinction is that the standardized values of the “raw” scores will be centered about their sample means and scaled (divided by) their sample standard deviations; that is:
How to calculate descriptive statistics for a variable?
In SPSS, the Descriptives procedure computes a select set of basic descriptive statistics for one or more continuous numeric variables. In all, the statistics it can produce are: N valid responses. Mean. Sum. Standard deviation. Variance. Minimum.
