Least Squares Optimised Fit Using Python— A Basic Guide

How do we choose a reasonable starting point when modeling some data? In the context of statistical inference, this question takes on a prominent dimension as we typically begin our analysis with a fairly simple model that represents the system or process, with reasonable accuracy. …

The Probability Density Function of a Natural Logarithm

I’ve been working in the log domain over the last couple of weeks, specifically using the natural logarithm, denoted by “ln”. Life has been easier this way. The dataset I’m working on has a component driven by a random variable X that is distributed normally (a Gaussian distribution) with mean…

Log Plots, Kernel Density Estimation and Experimental Data

I’ve been pretty busy working with some data from an experiment. I’m trying to fit a subset of the data to a model distribution/distributions where one of the functions follows a normal distribution (in linear space). Sounds pretty simple right? Based on the domain knowledge of this problem, I also…

NEAs — Exploring Sentry Data

I covered some asteroid and NEA basics in my last post. In this post, we will examine some NEA/NEO data and try and understand some metrics related to potentially hazardous/dangerous NEO (Near Earth Objects). Let’s begin. Our exploration starts with some publicly available data via the CNEOS API, specifically, I…

Near-Earth Asteroids — An Exploratory Analysis

Our Solar System is a strange place and there’s a lot we don’t know and don’t fully understand. There’s no better way to reflect on this point than to take a historical perspective. The discovery and characterisation of the planets and other bodies in our Solar System can serve as…
