Get the cost sensitivity information for an activity.

Cost sensitivity is measured by three sensitivity measures, as follows:

- Cruciality index (r): correlation between the activity cost and the total project cost using the Pearson's product-moment correlation coefficient.
- Cruciality index (rho): correlation between the activity cost and the total project cost using the Spearman's rank correlation coefficient.
- Cruciality index (tau): correlation between the activity cost and the total project cost using the Kendall's tau rank correlation coefficient.

These sensitivity measures are only available when the sensitivity parameter of the P2Simulator:run_simulation has been set to 1 during its execution.
