EFA vs. CFA - Exploratory vs. Confirmatory Factor Analysis

Factor Analysis & SEM Playlist: shorturl.at/jrxGI
In this video we will look what are the differences between Exploratory Factor Analysis (used to reduce the dimension of the data, and to find structure in it) and Confirmatory Factor Analysis (used to confirm if a model fits the data well enough).

many thanks for the lecture. we all the time need to know how the factors are calculated from the variables. but how come the factors and their loading can be calculated given that the only given data is the variables?
x1=l1f1 + l2f2 + l3f3

appreciate the video man

1. Can you resample the data if you can’t use other data? although im not sure about this one
2. Can you do CFA straight after EFA? and then can you do multiple regression on the outcome?
Thank you

great
