JazakAllah khairan kaseera brother.... This helped me alot

Easy and well explained. Thanks

THANK YOU Ameer S.

how we can estimate the scores of these variables?

Sir if we have some variable which is negatively related and some have positive relationship, so what should we do in that case. In normalization we have two different formulas for negative and positive relationship with defended variable for index making through normalization and aggrigation, but my question is what should we do if we apply PCA

hey thanks for the useful video. I have just one query, Do we need to standardize the variables when applying PCA command in STATA 17 or applying the PCA command will work only? will it automatically standardize the data when PCA cmd is applied? Thanks

Hello , I need information on how to calculate Livelihood Vulnerability Index. Thanks

Dear Sohaib Ameer. Being a professional we must follow the ethics and rules of every profession. You just run the pca command and predict the index without going in details analysis of the reslults. WE must ensure the credibility and reliability of the index that is going to represent an issue in the research paper. As I know the process of PCA is not much easy as you explained here. There are lots of things that being a researcher we must ensure.

Many thanks for this video. Very helpful. I want to understand a basic thing. Why is the weighted index value (here the fd) more than 1? It should ideally be 0-1. Can you please clear my doubt.

Sir how to find out the concentration index of inequality using STATA?

Hello, great work and illustrative. But, i guess you make not an index, this is each component you should be multiply by varianze factor 45%, 22% y 8%, if dont remember bad, the result is a global index and this is a FA not a PCA, if you had used a PCA just should be used just 5 variables and construct an index by this varaiables. By the way, in my opinio with two component is neccessary, the explained variance is almost 70%. Greetings and great work, again.

Thanks a lot. It is very useful.

You should clarify the basics like why PCA on which type of variables PCA is applicable. Hiw to scale different variables etc.

All variables are having positive values. But, your FD index is having both positive and negative values. As I understand, the index should not have negative values. How to interpret the negative index values?

Thank you!! Your video helped a lot!

well explained bro

Do stata standardized variables automatically?as you haven't standardized the variables. variables with different scales need standardization.

Thank you very useful. I want to construct an index using two-step PCA. This is the first step. Is it possible to shed light on 2 things: 1. How to carry out 2nd step when I get the results (prediction) from each dimension? 2. How to convert the result (prediction) to an index between 0 and 1

please tell which variables you have used to make FD

Thank you

Thank you so much for the video....🙏

can you please show me how to construct wealth index using SPSS?

How can I make the Index lie between 0 and 1 ?

Thank you so much

Can we do PCA for all the cross-sections (i.e. Pakistan, India etc) together?

Thanks so much so helpful < 3

Thank you. But I see one mistake. You found that it makes sense to take two components of the pca operation since it was showing an eigenvalue greater than 1 for the first 2 components, then why did you predict only the first component. This will lose a lot of information. You should've used: predict pc1 pc2

I want to calculate the weighted value based PCA of multiple criteria for the analysis of agricultural drought. Please tell me how can do it

hi, i just saw your video, not related to my problem. I want make the index of 5 different variables on the basis of decile rank. your cooperation considered highly appreciated in this regard.. thanks

thank you sir really more informative, sir if its possible plz upload a video about extreme bound analysis

How to get the score of each PC please

Where is the index

Thank you!!! You have simplified this process so well and understandable even by non-experts!!

Thank you so much, I couldn't figure it out for hours until I found this video. Literally a lifesaver

How do you construct the index then?

Can you please explain why did you rotate the values?

I think this was all about PCA but could not understand how to make index?

please show the scale of the variable representing financial development, i want an answer please..

hello, can you guide me about PCA, how to organize the data of compounds in excel for PCA and how to analyze? thanks

Shouldn't the base year be equal to 100 (or 1) for an index?

can you please say which variables did you take

What happens when i want 3 pc for my ibdex?

What is the purpose behind selecting regression while displaying factor scores??

बहुत अच्छा शुक्रिया!

Helps a lot

Many thanks Sohaib. It was a great video

very informative and helpful. Thank you sir for uploading

Hi, exactly what are the weigths for each variable? or how can i find it?

It is more informative video, thank you so much for that. How about if we have binary response for items (like tv) and combination with continuous variable (number of bicycle)? Can we use pca or polychoric pca? One more, what is the implication of negative fd value in you output?

How to treat messing values? I watched your video in spss. but stata menus dont have those options in spss. please answer Im in trouble.
