This is by far the best video on the internet to explain factor analysis and all the steps necessary! Great work!

[loogsnyakwardyoh]

the correct column name is "Unnamed: 0". df.drop(['Unnamed: 0'], axis = 1, inplace = True) works...

[백영래-ux]

df = drop(['unnamed:0'], axis=1, inplace = True) This one works.

Great video, helped out a lot it processing my data using factor analysis for my data science class.

[austin_adetunji]

Wow, this is great. i wish i can like this video multiple times

Thank you very much, final year computer science but very little experience in statistics etc. this was a massive help

If you have trouble w/factor analyzer:
1. Open cmd and paste: pip install factor_analyzer
2. Once it is successfully installed, paste the command again and get the file path it is downloaded in (first line after the command).
3. Follow the rest of the steps in the video.

where can I find your Jupyter notebook?

[tarunsiga]

Could you explain me on what basis the factors were selected in FactorAnalyzer

[rajeshghosh]

Even after appending the site package directory the factor_analyzer is not importing. Can you help?

[phanthilanhuong]

Thank you for your sharing and fantastic guiding

[inspiritlashi]

This is such a great video.. Thank you so much

i cant see the link to the dataset please

[aysenzumrutsonmez]

I had an ModuleNotFoundError for factor_analyzer in the first step. How i solve this error? Please help me

[veronicam]

Thanks!! this video was very helpful to me :D

[Sudo]

Please, tell me what the values in the matrix signify.

[diepnguyen]

Could you explain for me why I have different results while implementing Factor Analysis in Python and STATA? There are differences in both scree plot and the value of loading factors :(( Don't know which is the correct one now :( Thank you for your support!

When I type fa.fit(df), it tells me there is an error "ValueError: Found array with 0 sample(s) (shape=(0, 38)) while a minimum of 1 is required by FactorAnalyzer." but when I check my document there is not ligne with 0 values, what can I do please?

[elhamahmadi]

Hi, I have one question. if we want to use FA or PCA for feature selection of all types of data(without dropping string type of data) how can we do that? Is there any alternative to apply?
