Very nice explanation sir. Which software have you used for doing the animations sir?
@marccampo65588 ай бұрын
I just use PowerPoint for the animation. There is probably a better way!

@10:16 working across the rows wouldn't the NPV be 7/17 = 41.2% rather than 7/19 = 36.8% as you have listed?

I think I finally got it. I'm not describing the entire bit, but the only thing that made it clear to me. There are TWO variables. P variable and Alpha variable. Both variables get values. The alpha variable gets a standard value that is decided by the scientific field. For example, Alpha is set at 0.01 in drug testing. But Alpha variable is set at 0,05 in psychology. P variable is a variable that gets it value from the actual test. The value that the P variable gets must be smaller than the value of the field-specific value of the alpha value. If the P variable's value < Alpha variable's value, then we reject the null hypothesis. However, if the P variable's value is larger than the value of the Alpha variable, then we stick to the null hypothesis.

Bayes' Theorem and Breast Cancer Screening with mammography. Please update and re-upload this excellent informative video using current scientific data. Sensitivity and Specificity of screening digital mammography in a recent extensive Norwegian clinical trial were 54.1% and 94.2% respectively. So:0.01x0.541 0.01x0.541 + 0.99x0.058 or 0.00541 0.00541 + 0.05742 or 0.00541 0.06283 or 0.0861 or 8.61%! If a woman receives a positive mammography result for breast cancer the probability she actually suffers from the disease is only 8.61% Reference pubs.rsna.org/doi/abs/10.1148/radiol.2019182394

Dear Dr. Campo, I did two different test for detection of a bacteria in the same population. Is it possible to calculate PPV, NPV, Sensitivity and Specificity of each test Separately with out gold standard ? Could you guide me please. Thank you for your consideration and confirmation would be appreciated. Sincerely, Narjes
@marccampo65586 жыл бұрын
There are statistical techniques, such as latent class analysis, that can be used when there is no gold standard. But I am not familiar enough with the technique to guide you further.

Hi Professor Campo, the numbers during 8:42 don't seem to make sense, across the rows. Since 82+1= 83, not 81. I think it was supposed to be 80TP and 12 FN to even the numbers out. Please let me know if I'm missing something. This is Diana Y.
