Another good video. I wish you would elaborate more on probabilities, in particular when more than two categories come into play. How probabilities are reported when we have three categories? Furthermore, it would be good if this video was accompanied by some explanations about QDA
How can I calculate Probability without the curve hight that you told in ruclips.net/video/9SuIE_tGF-g/видео.html ? How can I calculate it by hand without any software?
To calculate the height of the curve, simply calculate the height of the normal distribution curve as explained here: ruclips.net/video/8OkGwS4WWP4/видео.html at about 10 min.
For example, 0.132 corresponds to the height, at 30.8, of a normal distribution curve with a mean of 32.29 and a standard deviation of one. If you like to know how to calculate the height of a normal distribution curve, watch: ruclips.net/video/8OkGwS4WWP4/видео.html
@@tilestats Got it. Thank you so much. I was able to substitute the values and get the answer. I am a beginner in Data science. I have some doubts in LDA equations and Probability of default calculation pertaining to credit risk. Is it ok to ask here?

Would love to see QDA...hopefully, he will do it sometime in the future.
Great video! Helped me to understand what LDA is quickly. Keep it up with the videos!
Thank you!
good video
Can you please let me know how to normalize weights after calculating eigen vector lda score function
That is explained in the video before this one:

Excellent video. How do you get 0.132 and 0.062 for a score of 30.8? Please guide me. Thank you

Thank you. Your video helps me a lot
Thank you!
Are those values 0.7,0.11 are eigen vectors?
Yes, those values works as the first eigenvector, but at minute 17:48 in the LDA video you have the eigenvectors with unit length.
Can you put a video on how to find decision boundary with LDA on multiclass data?
@@tilestats thanks for your reply
Good work.
Thank you!
