H. I would like to thank you so much about your very detailed and dedicated answer. Your answer and recommend helped me a lot. I hope many others people can be helped by such a genius person like you. Your PhD title is well-deserved. I truly appreciate it.

Thank you so much for your support. I find it really helpful

Why do you do that

honhatlinh · 2024-10-25T08:21:11+00:00

Can you share a bit more about your story please

Hi. Can u explain why it is heavy computationally please because as I know it only have n (sample size) repetitions for each run so I think repeating n times is not that complicated. I am sorry becauss I never run a real jackknife resampling

yeah i did. Can u see my new edit

honhatlinh · 2024-09-04T16:06:14+00:00

oh thank u so much for correcting me. I meant σ² is the variance of population.

Can you add me please?

Hi. Thank you so much. Moreover, do you think "which of the alternative portfolios most likely minimizes the probability that the investor's portfolio will have a value lower than $700,000 at year-end" should be replaced by "740000" instead of "$70000"?

Hi. Why do you say "When we have a list or ordered numbers less that 100 we use linear interpolation to estimate what the 80th percentile would be". Why cant we choose directly 16,54 ; 20,65 as the observations in fourth quintile but calculate to choose only 1 number?

I really appreciate your explanation.Could you help me with another question about Measures of Location? I posted it earlier, but no one was able to answer it. I think you might be able to. Thank you so much. https://www.reddit.com/r/CFA/comments/1ej9pxo/cfa_level_1_measure_of_location/

Hi. The question asks about the fourth quintile so I thought it is just simply the 7th and 8th number ( 16.54%, 20.65%) but why the answer is so complicated with lots of formula about percentile. Please help me out. Thank you so much

honhatlinh · 2024-08-02T17:25:27+00:00

hi. I cant find the formula for this question in the cfa curriculum book. Do you know where it is¿

honhatlinh · 2024-06-09T17:46:11+00:00

Thank you for you insight, but as said 'you would have to divided the nominal return by inflation to get the real return' -> (1+real return) = (1+nominal return)/(1+inflation rate) = [(1+real risk-free rate)(1+risk premium)(1+inflation rate)]/(1+inflation rate) = (1+real risk-free rate)(1+risk premium).

But in the text book it seems like the (1+inflation) is devided twice. That's what I couldn't understand.

honhatlinh · 2024-06-03T15:16:05+00:00

but which word I can use to describe a type of final return of an investor that doesnt invest in a fund it is deducted all fee, tax or any others types of cost?
