Thank you very much for publishing this kind of information. Sorry, I didn't undestand what are the subgroups. Could you please explain practical situation what would it to be?

[@bkrai]

If we collect 4 data points every hour 20 times for some process, then 4 is the subgroup size and 20 is number of subgroups.

[@afundou]

@@bkrai thank you very much for the answer. Sorry if I'm asking something too obvious, but, why can't I just treat each collected datapoint as "subgroup" and plot it into the chart?

Great & informative video👌🏼👌🏼

Thanks! :)

[@AnantaPradhan]

I would like to request you to post prediction using raster data. You are great as usual.

[@bkrai]

Thanks for the suggestion!

Thank you for sharing this video sir. Are you using kaggle notebooks for coding ? Also two questions. How to choose subgroup size ? If we have IoT sensor data for many parameters , can we do this multivariate control chart ? Any limitation on the count of parameters ?

[@bkrai]

For subgroups usually 3 to 5 work fine. For parameters, it supports up to 10.

Hello sir, I need to perform a MSPC analysis using one dependent variable and 4 independent variables. The dependent variable is boiler pressure and the independent variables are fuel flow rate, air flow rate, steam flow rate and fuel humidity. What is the best approach to perform the T2 hotelling test?

[@dollybell3388]

did you find out the answer? I'm interested in this too

Sir can we draw T square chart after finding PCA

Hello Sir, could you please explain about how to find a duplicate page in pdf document (pdf contains image and document) and deleting the duplicates using R?
