Good morning sir, I have collected 800 soil samples from different districts of Manipur State in India. The soil samples were analysed for different forms of soil acidity. Sir I wish to prepare a soil acidity map of Manipur state using my data. Sir Could you share some of your knowledge to prepare.
10:03 hat beta 1 = sum(x i - overline x )(y i - overline y ) sum(x i - overline x )^ 2 = sum(x i - overline x )y i sum(x i - overline x )x i = sum x i y_{i} - 1/n * (Sigma*x_{i})(Sigma*y_{i}) sum x i ^ 2 - 1 n ( sum x i )^ 2 . 😢Plz can u explain how the first equal to hat beta 1 has been derived 😢😢 have been trying to figure out since morning 😭 can't find my way around it
The answer should be yes, but I'm not sure you can do both at the same time. And you may need to do a "manual" version of this where you comment/uncomment parts of your YAML header to get the different behavior, requiring you to compile it two times.
Hi Joshua, Interesting video! I was experimenting with permutation tests in regression and found my p-values for coeffcients are simular to those generated by using a t distribution. The one exception seems to the p-values for the intercept term. Is there a reason for this? Do you know of any way to correct for it? Thanks.
What does "deploy is waiting for github-pages deployment approval" mean? I have completed all the same steps outlined in your videos but reach this point as part of the actions and I wait upwards of 10-15 minutes with no deployment of the page.
@@jfrench Thanks for the reply. I figured out the issue...I was using regular markdown files (.md) and not quarto files (.qmd) and fixing this seemed to allow my page to deploy!
