In this article we are going to learn about difference between violinplot() and boxplot() using Python. What is a violin plot? A violin plot is a type of statistical chart similar to a box plot but with a rotated kernel density plot on each side. The name "violin plot" comes from the fact that the chart's shape looks similar to a violin's shape. A violin plot is used to visualise a dataset's distribution and shows the data's probability density at different values. The violin plot displays the data distribution of the sample, with the thickest part showing where the values ... Read More

Density Plot A density plot, also known as a kernel density estimate (KDE) plot, is a graphical display of data that shows the probability density function (PDF) of the data. It is used to visualize the distribution of the data and identify patterns and trends in the data. The purpose of a density plot is to give you a visual representation of the underlying distribution of the data. It can help you understand the shape and spread of the data and identify any unusual values or outliers. It can also be used to compare the distribution of multiple variables or ... Read More

What is Swarmplot() and Stripplot? In python seaborn, the swarmplot() positions the points using a technique called "beeswarm" that adjusts the points to avoid overlap. This results in a plot where the points are spread out and are easier to distinguish, but the relative positions of the points within a category are not preserved. Whereas, stripplot() positions the points on a categorical axis, with one category per tick. The points are not adjusted to avoid overlap, so they may overlap if many points are in the same category. Feature stripplot() swarmplot() Purpose Display the distribution of ... Read More

A matplotlib-based Python data visualisation package is called Seaborn. It offers a sophisticated drawing tool for creating eye-catching and educational statistics visuals. Seaborn assists in resolving Matplotlib's two main issues, which are? We now believe that teaching students how to generate these representations using ggplot2's methods—which take more coding but are more advanced, adaptable, and transparent—will benefit students. Here, the basic plots made by residPlot() are rebuilt using ggplot2 as a resource to assist users in switching from residPlot() to ggplot2. Feature regplot() lmplot() residplot() Purpose Plot a simple linear regression model between two variables ... Read More

Pandas is a well-known open-source Python library that provides a wide range of capabilities to make data analysis more effective. The Pandas package is mostly utilised for pre-processing data activities, including cleaning, transforming, and manipulating data. As a result, it is a highly useful tool for analysts and data scientists. The two most popular data structures in Pandas—Series, and DataFrame—as well as the comparison of Series and vectors, are discussed in this article. Python Pandas Series In the Python Pandas library, a series is a one-dimensional labeled array that can hold any data type. It is similar to a column ... Read More

A memory cache is an element of software or hardware which holds frequently accessed data in a convenient location. A cache is used to improve system performance by reducing the amount of energy it requires to access data. The memory ability establishes how much data a cache can store. While the memory cache is full, some data must be evicted in order to provide a place for new data. Following this, there is the fact that the world is ending. The Least Frequently Used (LFU) cache storage replacement policy is one of these policies. Everything in an LFU cache has ... Read More

What is the importance of Data Analysis at present? The use of data analytics in finance is expanding globally. From big financial names to stock market analysis, financial markets rely on data analytics to better understand their consumers and trends. What are the skills required for Data Analysis? If you’re wondering who analyzes large datasets in a huge financial organization, financial data analysts are professionals who analyze the data of any organization to make accurate business decisions for their company. One of their key responsibilities is analyzing and assessing the firms' financial information. Often, in a firm, Financial Data ... Read More

Introduction Machine learning is a common topic in the technology and business world. Machine learning is a technology that processes the raw data, provides helpful information, including data prediction and analysis, and releases final statistics reports. In short, ML helps process the data and produces reports to achieve the set goals. It uses various high-end algorithms and paradigms to engage with the solutions. Artificial Intelligence is the fastest-growing technology under which machine learning and deep learning work. In this article, you will see the top 7 hackathons and technical events of machine learning, that are organized worldwide. This includes ... Read More

Introduction The Grubbs test is a statistical hypothesis testing method to detect outliers in a dataset. Outliers are the observations that disburse the data distribution and are also known as anomalies. The dataset with outliers tends to overfit more than data with a Normal/Gaussian distribution. Hence, it is necessary to tackle the outliers before Machine Learning modeling. Before handling, we must detect and locate the outliers in the dataset. The most popular outliers detection techniques are QQPlot, Inter-Quartile range, and Grubbs statistical test. However, this article will discuss only the Grubbs test to detect the outliers. You will learn: what ... Read More

Statisticians use F-test to check whether the two datasets have the same variance or not. F-test is named after Sir Ronald Fisher. To use the F-Test, we make two hypotheses, a null hypothesis, and one alternate hypothesis. Then we select any of these two hypotheses approved by the F-Test. Variance is a data distribution metric to tell the data deviation from the mean. The higher values show more dispersion than the smaller values. In this article, you will learn how to perform an F-Test in Python programming Language with its use cases. F -Test Process The process to perform the ... Read More
