## Explanatory Variable & Response Variable: Simple Definition and Uses

An informative variable is a kind of free factor. The two terms are frequently utilized reciprocally. However, there is an inconspicuous distinction between the two. At the point when a variable is autonomous, it isn’t influenced at all by some other factors. At the point when a variable isn’t autonomous for certain, it’s an […]

## Dot Plot in Statistics: What it is and How to read one

Dot Plot: Definition A Dot Plot additionally called a  A Dot Plot, also called a dot chart or strip plot, is a type of simple histogram-like chart used in statistics for relatively small data sets where values fall into a number of discrete bins (categories). A dot plot is like a structured presentation in light […]

## An Introduction to Decision Tree

Machine learning is becoming more and more sophisticated. So much so that it can help with decision making too. A decision tree is essentially a layout of various outcomes associated with a series of choices related to each other. Organizations and individuals can utilize it to weight their actions based on multiple factors such […]

## Convolution

Introduction Convolution is a mathematical operation that makes the product integral of 2 functions (signals), with one of the signals upside down. For instance, below we convolve 2 f(t) and g(t) signals. So the first thing to do is to flip the g signal horizontally (180 degrees), and then slide the g upside down on […]

## Sensitivity Analysis

What Is Sensitivity Analysis?  An affectability investigation decides how various estimations of a free factor influence a specific ward variable under a given arrangement of suspicions. At the end of the day, affectability investigations study how different wellsprings of vulnerability in a scientific model add to the model’s general vulnerability. This system is utilized inside […]

## Variance-Covariance Matrix

This lesson explains how to use matrix methods to generate a variance-covariance matrix from a matrix of raw data. Variance Variance is a proportion of the fluctuation or spread in a lot of information. Scientifically, it is the normal squared deviation from the mean score. We utilize the accompanying equation to figure change.  Var(X) = […]

## R-Squared Definition

What’s R-Squared? R-squared (R2) is a statistical measure representing the proportion of the variance for a dependent variable that is explained by one or more independent variables in a regression model. While correlation explains the strength of the relationship between an independent variable and a dependent variable, R-squared explains the extent to which the variance […]

## Regression Equation: What it is and How to use it

Regression equation: Overview A regression equation is used in statistics to find out what relationship, if any, exists between data sets. For example, if you measure the height of a child each year you might find that it grows about 3 inches a year. This trend (which grows by three inches per year) can be […]
