What is a latent variable?

Hint: Here we can see about latent variables. We should know the Latent variables are variables that are not directly observed but rather inferred, through a mathematical model, from other variables that are observed. It is also used in day to day life, we can now see about it with an example.

Complete step by step solution:
Here we can see about latent variables.
We should know that latent variable is a variable which is not directly observed and is assumed to affect the response variable.
Latent variables are variables that are not directly observed but rather inferred, through a mathematical model, from other variables that are observed.
The simplest approach to measuring a latent variable is to find a single observed variable that is believed to be a sufficiently accurate measurement of the latex variable.
In daily life, if we want to ask people any questions, we can ask them directly or if you want to gauge intelligence, you can present people with difficult mathematical questions.
We can now take an example sentence,
“Einstein would not have been come up with his \[e=m{{c}^{2}}\] as he had not possessed such an extraordinary intelligence”
We can see that it relates the observable behaviour (Einstein writings \[e=m{{c}^{2}}\]) to an unobservable attribute (his extraordinary intelligence).

Note: We should remember that Latent variables are variables that are not directly observed but rather inferred, through a mathematical model, from other variables that are observed. The simplest approach to measuring a latent variable is to find a single observed variable that is believed to be a sufficiently accurate measurement of the latex variable.
