Statsmodels is a comprehensive Python library designed for statistical modeling, econometric research, and data analysis. It provides a robust framework for estimating and diagnosing a wide range of statistical models, enabling users to perform rigorous hypothesis testing, regression analysis, and complex data exploration within structured environments. The library distinguishes itself through its support for advanced statistical methodologies, including state space representation for dynamic systems and generalized linear frameworks that accommodate non-normal response variables. It offers s

This project is a Python financial analytics framework and quantitative trading library. It provides a suite of mathematical tools for asset pricing, statistical market analysis, and the development of algorithmic trading strategies. The library is distinguished by its focus on currency and commodity correlation modeling, using regression and normalization to identify exchange rate drivers. It features a specialized portfolio optimization engine that applies graph theory, such as clique centrality and degeneracy ordering, alongside quadratic programming to balance risk-adjusted returns. The

OSMnx 是一个 Python 库，用于从 OpenStreetMap 下载、建模和分析街道网络及其他地理空间特征。它使用户能够检索和处理世界各地的现实基础设施数据，提供用于网络分析、空间查询和可视化的工具。 该库提供了处理城市特征（如建筑轮廓、公交站点和高程数据）以及网络统计信息（如交叉口密度和迂回度）的功能。它支持多种出行模式，包括驾驶、步行和骑行，并可以计算最短路径、推算行驶速度和生成等时线地图。其他功能包括地理编码、地图匹配、坐标投影以及以各种格式保存和加载网络的能力。 OSMnx 提供了将街道网络和地理空间特征可视化为静态地图或交互式 Web 地图的工具，并可以绘制图底图。该库可通过标准 Python 包安装方法获取。

This is an interactive notebook-based course that teaches machine learning from Python fundamentals through deep learning and natural language processing. It uses real datasets and multiple frameworks within a structured, hands-on curriculum that combines concise explanations with executable code cells, built-in datasets, and embedded exercise checkpoints. Learning progresses through data preparation and exploration, classical machine learning workflows, computer vision with convolutional neural networks, and natural language processing with deep learning, all delivered as a cohesive progressi

Geolib 是一个地理空间计算库和点分析工具。它提供了一系列用于计算坐标之间距离、方位角和面积的工具，以及转换地理测量值和坐标格式的功能。 该库具有一个 Well-Known Text (WKT) 几何解析器，可将 WKT 字符串转换为用于多边形分析的坐标结构。它包括用于地理围栏和点包含分析的专用工具，能够确定坐标是否落在定义的多边形或指定半径内。 该工具集涵盖了广泛的功能领域，包括位置邻近度分析、导航方位角计算和数据转换。它可以计算中心点、确定边界框并按邻近度对坐标进行排序，以识别最近邻居。 该库还提供用于验证坐标以及在不同公制和英制标准单位之间转换距离、面积和速度的工具。
