v.22.6Improvement

Using CDF Functions Instead of Numerical Integration for Improved Speed and Precision

Official CH changelog text
Do not calculate an integral numerically but use CDF functions instead. This will speed up execution and will increase the precision. This fixes #36714. #36953 (Nikita Mikhaylov).
Replaced numerical integral calculation with CDF functions to improve execution speed and precision.

Why it matters

The feature solves performance and accuracy issues by avoiding numerical integration in favor of using cumulative distribution function (CDF) calculations, resulting in faster query execution and higher numerical precision.

How to use it

Users benefit from this improvement automatically as it is applied internally in relevant computations. No explicit user action is required to enable this feature.
