Dart Comments Comments are non-executable lines of text within a program that are ignored by the compiler or interpreter. They serve the purpose of providing explanations, annotations, or context within the codebase. While comments are not directly involved in the program’s execution, they are invaluable for developers to understand the code’s intent, functionality, and design […]
Keywords in Dart Keywords are reserved words in Dart that have predefined meanings and cannot be used as identifiers such as variable names or function names. These words are integral to the language’s syntax and are used to define control structures, data types, and various other elements within a Dart program. In the below PDF
Data Types in Dart Data types in Dart define the type of data that a variable can store. They specify the size and type of values that can be stored in an identifier. Dart, being a statically-typed language, requires variables to be declared with a specific data type before they can be used. In the

Variables in Dart A Variable is a container that holds a value. This value can be of various types, including numbers, strings, boolean values, lists, maps, and more. Variables allow programmers to store data temporarily or permanently and manipulate it as needed throughout the program’s execution. In the below PDF we discuss about Variables in detail

Introduction to Dart Dart is an open-source, general-purpose programming language developed by Google in 2011. It was created with the goal of providing a productive and efficient way to build web, mobile, and desktop applications. Dart was designed to address some of the shortcomings of existing languages and frameworks, offering developers a modern toolset for

Residual Analysis Residual Analysis is a fundamental technique used in data science and statistical modeling to assess the goodness-of-fit of a regression model and to identify patterns or trends in the model’s residuals. Residuals are the differences between the observed values and the predicted values from the regression model. Analyzing residuals helps to validate the

Linear Regression in Data Science Linear Regression is a statistical method used to model the relationship between a dependent variable and one or more independent variables. It assumes a linear relationship between the variables, hence the name. The goal of linear regression is to find the best-fitting line that describes the relationship between the variables,

One Hot Encoding One Hot Encoding is a process used to convert categorical variables into a numerical format that can be provided to machine learning algorithms to improve their efficiency and effectiveness. Categorical variables are those that represent categories, such as colors, types of cars, or cities. These variables are non-numeric in nature and cannot
Data Transformation and Techniques Data Transformation is the process of converting raw data into a more structured and usable format for analysis, visualization, and decision-making. It involves various techniques such as cleaning, filtering, aggregating, and integrating data from disparate sources to create a unified and coherent dataset. In the below PDF we discuss about Data

Covariance and Correlation Covariance and correlation are two statistical measures used to quantify the relationship between two variables in a dataset. While both measures assess the degree to which variables change together, they differ in their interpretation and scale: Covariance:Covariance is a measure of the degree to which two random variables change together. In simpler
