Sampling Methods and Algorithms in Data Analysis: Nonprobability Sampling
In our previous article, we discussed probability sampling, a method where samples are selected randomly, giving each population member an equal chance of inclusion. This article will explore nonprobability sampling, a technique where samples are chosen based on criteria other than random chance. Before delving into nonprobability sampling, let...
Sampling Methods and Algorithms in Data Analysis: Probability Sampling
Sampling is a fundamental process in data analysis. It involves selecting a subset of individuals from a larger population to study. By analyzing this sample, researchers can draw reliable conclusions about the structural and statistical properties of the entire population. In this article, we will look into the classification of sampling technique...
Improving Employee Skills in Data Science
The world is awash in data, yet we struggle to fully capitalize on its potential due to a severe shortage of skilled professionals. A significant mismatch persists between the demand for data scientists and analysts and the available talent pool.

Features of Working With NULL in Megaladata
Empty values in data can create serious difficulties in processing. Using the NULL value allows you to avoid the uncertainty that arises when operating with them. Let's consider how to correctly process sets of such data.
From Data to Knowledge: There and Back Again
Among the new capabilities of the Megaladata platform, we would like to highlight the two strategies of workflow design: "upwards", from data to models, and "downwards", from models to data. This combination enables a more flexible modeling process, even allowing for the creation of analytical workflows without requiring data up...
