- This video is all about survival time analysis. We start with the question what a survival time analysis is, then we come to the important point what the censoring of data means and finally we discuss the Kaplan Meier Curve, the log rank test and the Cox regression.
Survival time analysis is a group of statistical methods in which the variable under study is the time until an event occurs.

Love the pace! Great examples and explanation, thank you a lot!
Being a graduate in the domain of Public Administration where the curriculum mostly focused on theoretical discussions, I have started an extended academic journey in the field of 'Data'. Your video is so helpful. Helped me to easily understand the basic concept. Definitely, I will follow through. Thanks a lot! Best wishes.
In regards to the tooth fillings you would have to install the two types in the same mouth (person) for the study to be signficant. Otherwise mouth chemistry and other "confounders" might skew the results. You also have to have the same dentist do these fillings since there may be difference in the quality of the dentistry form one dentist to another.
May God bless you!!. Your videos and explaining are more than amazing. Actually they are beyound description.
Wow! Perfect video on this topic. I didn't expect such material exist.
Glad you liked it!
Awesome explaination, thanks!
Amazing video! Easy to understand. Thanks very much!!!

Very clear!! Thanks 🎉
Great Video! Thanks
👏👏👏
Glad you liked it!
I have exam about this tomorrow, you really save my day
Thank you :)
Happy to help!
this is really great
Great video!
Hi @DATAtab , may i know why survival is focusing on predicting probability rather than a single value ? As per the definition survival outcome is to predict duration ( time to event ). Thanks
Coz every prediction is "likely" to be wrong. So, there is always some uncertainty. N where there is uncertainty, there is probability.
Really really thank you!
great video...thank you
Glad you liked it!
perfect video!!!
Great video 👏
Thanks : )
Great vídeo, i would really apreciate if you make one computating in R.
Tanks
Thanks for the idea! But datatab finances me that I can create free videos : )
Just wooow thank you
You're welcome 😊
So, a quick question is a survival analysis possible without censored data?
Strictly speaking one does not "retain" the null hypothesis. One "fails to reject it".
if you want to know the mortality at 5 years, and persone A dies at 6 years and person B drops from the study at 3 years (so two years before your measuring point).
And you make a table from this data: do you consider both data as censored? and what do you will in in the table? Should you fill in person A: No ( so it did not die at year 5) and for person B not fill anything ( so not Yes and not No)?
Mate, I found your question ambiguous. So, sorry, if this doesn't answer your Q.
If question is to know how many will be alive in 5 years, then both the data points you mentioned would be part of analysis, since one passed away in 3 yrs (before the threshold) & the other after the threshold (6yrs). So, neither data point would be censored.
can i get pdf files please
