“The CPI measures the change in prices UK consumers pay for everyday goods and services, like groceries, fuel and clothing. It compares the prices of goods and services now with how much they cost a year ago. The Office for National Statistics (ONS) calculates and releases an updated figur...
What does the smaller number beside the variable mean in Statistics? The i-th position In Elementary Statistics and Probability Theory, the little number next to a variable, say the i inXirepresents the i-th position of said variable. These types of subscripts are commonly seen when ...
These facets of knowledge represent thecontextthat is often missing from data. When traditional data management systems attempt to capture context, they fail. These failures generate gridlock over mastering data, delay timelines when adding new data sources or properties, and cause missing datasets from...
Anomaly detection has a long history in statistics, driven by analysts and scientists who pored over charts to find elements that stood out. Over the last several decades, researchers have started automating this process usingmachine learningtraining techniques designed to find more efficient ways to ...
Identify and remove duplicate records.When two records seem to repeat, an algorithm needs to determine if the same measurement was recorded twice or if the records represent different events. In some cases, there may be slight differences in a record because one field was recorded incorrectly. In...
comparing total scores or section scores from the current version of the exam to the GMAT Focus Edition is not appropriate, accurate, or a meaningful comparison of performance," Dharia said in the press release. "Scores of 600 and 605 may look similar, but they represent very different p...

Our ability to measure the critical quality attributes of active moieties in medicines is improved with advances in technologies. These can represent the analytical standards used to calibrate both products and equipment. Many of the analytical parameters may be directly clinically relevant, like levels...
For training image recognition systems, the data should represent what the model will see in the real world. That includes subjects in shadows, slightly out of focus, and not looking directly into the camera. For training purposes, the more data resembles what the system will see in production...
Modeling provides results in the form of predictions that represent a probability of the target variable (for example, revenue) based on estimated significance from a set of input variables. This is different from descriptive models that help you understand what happened, or diagnostic models that ...
