Demystifying the confusion about Linear Regression Visually and AnalyticallyImage: Linear regression illustration, by Stpasha, via Wikimedia Commons (Public Domain). Original Image Link: https://upload.wikimedia.org/wikipedia/commons/8/87/OLS_geometric_interpretation.svgThe above image represents a geometric interpretation of Ordinary Least Squares (OLS) or Linear Regression (words used interchangeably in classical statistics). Let’s break down what we’re seeing in an intuitive way:Variables (X1 and X2): Imagine you have…

China's Zhurong rover was equipped with a ground-penetrating radar system, allowing it to peer beneath Mars's surface.Researchers have announced new results from the scans of Zhurong's landing site in Utopia Planitia, saying they identified irregular polygonal wedges located at a depth of about 35 meters all along the robot's journey.The objects measure from centimeters to tens of meters across. The scientists believe the buried polygons resulted from freeze-thaw cycles on Mars billions of years ago, but they could also…

We are required to analyze the pattern or rule followed by the numbers and find out the number that fits into the blank segment. Some of the problems contain two or more similar geometrical figures, instead of one. In such problems, a blank space is left only in one figure. We are required to analyze and identify the pattern of numbers in the…
