Solved – pooled OLS VS multiple linear regression

panel datapooling

somebody help me to understand the difference between pooled OLS vs multiple linear regression.

i learned panel data analysis consists of three: 1. pooled OLS 2.fixed 3. random

my understanding about pooled OLS is that it disregards the space and time dimensions of the pooled data and just estimate OLS regression.

and my question is there any difference between pooled OLS and multiple linear regression?

Richard Hardy answered the question in the comments, but I'm reposting his comment as an answer for completeness:

Multiple linear regression is a very general thing that can be applied in many different settings. Meanwhile, pooled OLS comes from a panel data context and thus it is not as general. However, by specifying pooled OLS you are specifying a multiple linear regression. That is, pooled OLS could be treated as a special case of multiple linear regression.

So yes. Pooled OLS is multiple linear regression applied to panel data.
