Dr Neil, I came back here to thank you so much

Thank you Samir for taking time to comment. Glad it has been helpful.

[@karannchew2534]

Note for my future reference/revision. Step (a vertical line) = death. Longer vertical line: more likely censor occurred prior to that If censored (e.g. subject left the study) →study subject # reduces, →denominator of hazard rate reduces, →hazard rate increases, →survival rate decrease steeper (might observe some delay if censor happened over a period of time?)

[@dramygdala8798]

Hi sir. At 13:38, you said the curve drops by 2/9 percent and you shoul have 9 sections remaining. Shouldnt it be 1/9% as we already accounted for the first person with MI at the first drop in the curve? And shouldnt there be 8 sections remaining as 2 people have had events out of 10? Thank you!

Today I completed watchig all of your biostatistics playlist. It was handsdown an amazing experience. I really dont know here I would be without these today!!!. Thank you so much Dr Randy!!!. One personal request please make a video on all kinds of risks (Atributable risk, Absoulute risk reduction etc) specifically focussing on those!!!!!.

[@umerhayat6857]

where*

Umer, I'm glad the videos have been helpful. I think some of those topics are buried within some videos... I just don't recall which ones at this time.

[@umerhayat6857]

@@RandyNeilMD Yes Dr. Randy!!! You’re right those topics are present in some of the initial videos of biostats but what I meant was; A video that primarily focuses on the risks in a way that all of them can be solved and differentiated with questions!!. Lately aside from Relative Risk, all other have been presenting in a very twisted way!! :(
