Feed: Featured Blog Posts - Data Science Central. Author: Clayton Davis. As your team invests significant time and resources developing models, it is imperative that processes are put into place to protect and maximize the return on that investment. To that end, in this installment of the ModelOps Blog Series we’ll discuss leveraging functionality provided by continuous integration/continuous deployment (CI/CD) frameworks such as Jenkins, CircleCI, and GitHub Actions to automate the push of model container images to production container registries. As your team develops and containerizes models, it’s important that they don’t just live on your R&D servers or model ... Read More

Binomial Distribution in R, Binomial distribution was invented by  James Bernoulli which was posthumously published in 1713. Let n ( finite) Bernoulli trials be conducted with probability “p” of success and “q” of a failure. The probability of x success out of n Bernoulli trials is given by f(x)=(ncx)pxqn-x where x=0, 1 ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: Evan Morris. The distribution of data means the way the data gets spread out. This article talks about some essential concepts of the normal distribution: How to measure normality Ways to transform a dataset to fit the normal class distribution How to use the normal distribution to showcase naturally distributed phenomena and provide statistical insights Let’s get started! Suppose you belong to the field of statistics. In that case, you know how vital data distribution is because we always sample from a population where you have no idea about full distribution ...

Circular statistics deals with analysis of measurements made using a circular scale, e.g., minutes past the hour, days of the week. Wikipedia uses the term directional statistics, the traditional use being measurements of angles, e.g., wind direction. Package support for circular statistics is rather thin on the ground ...

Weibull Distribution in R, Weibull Distribution was discovered by Swedish physicist Wallodi Weibull in 1939. A continuous random variable X is said to follow Weibull distribution if its probability density function fx(x; α, β)= α/βα [x α-1e(-x/ β)^α] For x>0, α, β>0. There are two parameters in this distribution and It can ... Read More

Feed: R-bloggers. Author: Ronan Harrington. Introduction In this post, the BEA Infrastructure Investment data set from the #TidyTuesday project is used to illustrate variable transformation and the exploreR::masslm() function. The variable for gross infrastructure investment adjusted for inflation is transformed to make it less skewed. Using these transformed investment values, multiple linear models are then created to quickly see which variables in the data set have the largest impact on infrastructure investment.

Feed: SAS Blogs. Author: Ron Cody. This post demonstrates how to rank data and how to place these ranks into roughly equal groups. There are certain variables, such as annual salary, that are highly skewed. There are many who earn between $50,00 and $150,000, but some who earn millions or hundreds of millions of dollars a year. Trying to use variables like annual salary in statistical models typically violates assumptions of many popular statistical techniques. There are several solutions to the types of distribution problems we just described. One solution is to use a transformation like a logarithm of a ... Read More

Feed: AWS Public Sector Blog. Author: Ray Rogers. Healthcare organization Dr. B launched to get as many COVID-19 vaccines into as many arms as possible. To achieve its mission to make access to care—specifically the COVID-19 vaccine—more efficient and equitable, the company created a serverless solution built on Amazon Web Services (AWS). After a simple, 2-minute sign up, Dr. B is able to send individuals text message alerts when local providers have COVID-19 vaccine doses available. For healthcare providers, Dr. B simplifies vaccine distribution to help reduce the waste of unused doses. This was particularly critical in the early days ... Read More
