From g's perspective, it contributes dg to the whole [it doesn't know about f]Every change to a system is due to some part changing (f and g). If we add the contributions from each possible variable, we've described the entire system.df...
Two variables could depend on a third unknown variable. All of these aspects of correlation and how data variables are dependent or can relate to one another get us thinking about their use. Correlation is very useful in data analysis and modelling to better understand the relationships between...
The Kronecker Delta is defined\delta^i_j =1when i = j else 0. It's the way to write the identity matrix in Tensor notation. We get that because when we take partials of one independent variable with respect to another,\frac{\partial z^i}{\partial j}, we'll get zero unless the ...
advocates. Conversely, they really don't like spending time and effort on activities they don't agree with. Don't be intimidated by their questions; if they're pressing you, it's likely because they're trying to get on board by making sure they agree with and understand what ...
If x and y depend on the same variable (like t, time), we can write the following: It's a bit of the chain rule -- we're combining two perspectives, and for each perspective, we dive into its root cause (time). If x and y are otherwise independent, we represent the deriva...

Regression analysis shows the effect of independent variables on a dependent variable. For example, a rental car company may use regression analysis to determine the relationship between wait times and number of bad reviews. Diagnostic analysis: Why did it happen? Diagnostic analysis, also referred...
Input/Output tables, often referred to as function tables, are a foundational tool in mathematics to understand the relationship between two variables. Typically, one variable (the input) determines the value of the other variable (the output). In this guide, we’ll delve into the concept ...
To understand how to interpret a regression model with significant independent variables but a low R-squared, we’ll compare the similarities and the differences between these two models. Regression Model Similarities The models are similar in the following ways: ...
When we want to compare two or more data sets, the coefficient of variation is used. The CV is the ratio of the standard deviation to the mean. And because it’s independent of the unit in which the measurement was taken, it can be used to compare data sets with different units or w...
