商品描述

These days it seems like everyone is collecting data. But all of that data is just raw information -- to make that information meaningful, it has to be organized, filtered, and analyzed. Anyone can apply data analysis tools and get results, but without the right approach those results may be useless.

Author Philipp Janert teaches you how to think about data: how to effectively approach data analysis problems, and how to extract all of the available information from your data. Janert covers univariate data, data in multiple dimensions, time series data, graphical techniques, data mining, machine learning, and many other topics. He also reveals how seat-of-the-pants knowledge can lead you to the best approach right from the start, and how to assess results to determine if they're meaningful.

商品描述(中文翻譯)

這些天似乎每個人都在收集數據。但所有這些數據只是原始資訊,要使這些資訊有意義,就必須將其組織、過濾和分析。任何人都可以應用數據分析工具並獲得結果,但如果沒有正確的方法,這些結果可能是無用的。

作者Philipp Janert教導您如何思考數據:如何有效地處理數據分析問題,以及如何從數據中提取所有可用的信息。Janert涵蓋了單變量數據、多維數據、時間序列數據、圖形技術、數據挖掘、機器學習等許多主題。他還揭示了直覺知識如何從一開始就引導您找到最佳方法,以及如何評估結果以確定其是否有意義。
