How to choose between variables?

Pearson's #correlation is irrelevant if you suspect that the relationship is not a straight line.

If monotonic relationship:
"#Spearman’s rho is particularly useful for small samples where weak correlations are expected, as it can detect subtle monotonic trends." It is "widespread across disciplines where the measurement precision is not guaranteed".
"#Kendall’s Tau-b is less affected [than Spearman’s rho] by outliers in the data, making it a robust option for datasets with extreme values."

Summer Olympics soon in #Paris, expecting millions of visitors. CDG is the largest airport in Europe (in size) and second busiest (behind LHR). I may have clocked more steps in #CDG than in Paris city on this trip 😆

Anyway just wanted to say, hyvää juhannusta! Happy #midsummer!

(Even though I was in Paris for #AIDev this week, I hardly saw anything in the city aside from the conference venue, meetup venue, and my hotel. Need to return for a proper visit sometime but maybe after the Olympics..)
