Restricted cubic spline regression (RCS) R code implementation based on the rms package
1. Principle Restricted cubic spline (Restricted cubic spline, RCS) is one of the most common methods for analyzing nonlinear relationships. RCS uses a cubic function to fit the curves between different nodes and connect them smoothly, thereby achieving the process of fitting the entire curve and testing its linearity. As you can imagine, the number […]

Java uses ArcSoft SDK to implement face detection, feature extraction, and comparison
Recently, the company has a business scenario that requires the use of face recognition function. I just took this opportunity to write this article to consolidate my poor skills~ Without further ado, let’s get started! 1. Environment preparation: JDK1.8 + SpringBoot + Maven 2. Download Arcsoft SDK Go to ArcSoft Developer Center Create a new […]
How to do survival analysis with restricted cubic splines (RCS)?
1. Introduction In the fields of medicine and statistics, survival analysis is an important method for analyzing the length and survival time of individuals. Understanding how long people live and the factors that affect them is critical to formulating health policy, optimizing the allocation of medical resources, and developing individual care plans. Traditional survival analysis […]
H5 online CAD implements a way to draw arcs
Foreword Online CAD drawing arcs is essentially editing DWG drawings on the web page, and the DWG format cannot be edited directly on the web page, so you must first install the background conversion program of the dream CAD control, convert the drawings into mxweb format, and then send it to the front desk For […]
[Boolean difference operation for any polygon]: both straight lines and arcs are acceptable
Want to implement an algorithm by yourself to handle the Boolean intersection of polygons with arcs, the following is a basic idea and sample code: Approximate Arc as Multiple Line Segments: Divides the arc into multiple small line segments. This can be achieved by dividing the range of radians into a series of small angles, […]
