Background A user on Stackoverflow recently asked a question about a program to generate Monte Carlo simulations on Bernoulli trials to calculate coverage percentages using Wald confidence intervals. One of the problems in the code is that probability value calculations are executed on individual observations rather than sums of successes and ... Read More

So it is time to present it. This package allows to get confidence intervals about the quantiles of any reasonable distribution (although the inference is based on a parametric model). The statistical inference is fiducial. To give an illustration, I’m taking a sample of ... Read More

Feed: Recent Announcements. This new detector improves code quality by generating recommendations associated with five types of metrics. Metrics include: (1) method source lines of code, which measures the number of lines of code in a method; (2) method cyclomatic complexity, which measures decisions that are made in a method; (3) method fan out, which measures how many methods are called by a given method; (4) class fan out, which measures how many other classes are referenced by a given class; (5) class cohesion, which measures whether a class is designed with a single, well-focused purpose.  Amazon CodeGuru is a ...

Feed: Featured Blog Posts - Data Science Central. Author: Bill Schmarzo. This blog was originally written in 2012, and am republishing it because with the increased use of black box AI / ML models to power key operational decisions, these human decision-making traps need to be thoroughly and holistically addressed during the analytics definition stage to avoid the dangers of unintended consequences. Organizations are looking to integrate big data and advanced analytics into their business operations in order to become more analytics-driven in their decision-making.  However, there are several challenges that need to be addressed in order to make that ...

Feed: Recent Announcements. AWS Ground Station is a fully managed service that lets you control satellite communications, process satellite data, and scale your satellite operations. A mid-latitude AWS Ground Station located in the middle of the Pacific reduces the time between contacts for Low-Earth Orbit satellites and is useful for customers whose operations require downlink in this area of the world. Global expansion to Hawaii now enables satellite owners and operators to connect with their satellites and process their space workloads more frequently. Governments, businesses, and universities can benefit from more timely satellite data to make precise, data driven decisions ... Read More

Feed: Recent Announcements. Instance warm-up defines the number of seconds it takes for a newly launched instance to warm up. Once the specified warm-up time expires, the instance is counted toward the aggregated metrics of the Auto Scaling group (ASG), and CAS proceeds with its next iteration of calculations to estimate the number instances required. This prevents the ASG from adding more instances than needed. Before this launch, the instance warm-up time was set to a default value of 300 seconds. Now, you can specify a custom instance warm-up time either when creating a new capacity provider or updating an ... Read More
