How is violinplot() different from boxplot()?
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 MoreWhat is the purpose of a density plot or kde plot?
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 MoreWhat is the Difference between stripplot() and swarmplot()?
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 MoreDifference between regplot(), lmplot() and residplot()?
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 MoreDifference between series and vectors in Python Pandas
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 MoreHow to escape any special character in Python regular expression?
Regex, often known as regexp, is a potent tool for finding and manipulating text strings, especially when processing text files. Regex may easily replace many hundred lines of computer code with only one line. All scripting languages, including Perl, Python, PHP, JavaScript, general-purpose programming languages like Java, and even word processors like Word, support Regex for text searching. Regex may be challenging to learn because of its complicated syntax, but it is time well spent. Special Characters Text processing becomes more challenging when special characters are included because context must be carefully considered. You must think about what you see, ...
Read MoreHow to match whitespace in python using regular expressions
Regular expressions, often known as RegEx, are a string of characters corresponding to letters, words, or character patterns in text strings. It implies that you may use regular expressions to match and retrieve any string pattern from the text. Search and replace procedures benefit from the usage of regular expressions. The most common application is searching for a substring that matches a pattern and substituting something else. What are whitespace characters? "Whitespace" refers to any letter or set of characters representing either horizontal or vertical space. Using regular expressions, the metacharacter “\s” matches whitespace characters in python. Algorithm ...
Read MoreHow do we find the exact positions of each match in Python's regular expression?
Introduction The re-module is what we use in Python for regular expressions. Text searches and more complex text manipulation employ regular expressions. Tools like grep and sed, text editors like vi and emacs, and computer languages like Tcl, Perl, and Python all have built-in regular expression support. The re-module in Python offers functions for matching regular expressions. A regular expression that defines the text we are looking for or modifying is called a pattern. Text literals and metacharacters make up this string. The compile function is used to create the pattern. Raw strings are advised since regular expressions ...
