How to implement analytics?

Question

Analytics

Hello. As you work, after a while you will need to write an analytics service. I would like to get basic knowledge on the topic of how analytics is created, having some data. Both from the side of mathematics and from the side of programming. Perhaps some libraries are ready. I understand that I am trying to scoop up the whole ocean now, but still. Articles, books and more. I would be very grateful.

What do I mean by analytics.
There is user data. These are his actions. They are consistent and similar. I will need to draw conclusions from this data. For example, at one o'clock in the afternoon he is in this place (I have such parameters as time, location, user). And I received such data about this user for a month. Further, according to their algorithms, offer the user any content.

Answer 1

This is not analytics, this is DataMining.
In fact, this is a weighted daily parameter map.
Let there be 4 criteria (places to visit): home, work, my store, competitor's store.
Day 1: 1110
Day 2: 1101
Day 3 :1110
Day 4 :1101
Day 5 :1101
Crossing sets:
Total: 5523
It can be seen that the user did not skip work and always returned home, but he liked the competitor's store more than mine.
Further - your algorithms already make the necessary selection based on the final weight of the parameters (5523)
