    Coherent Risk Measure - Monotonicity

    This post may help. https://forum.bionicturtle.com/threads/coherent-risk-measure.4723/ . while Dowd (FRM assigned; he gives your expression above, that I copied of course) says "Let X and Y represent any two portfolios’ P/L (or future values, or more loosely, the two portfolios themselves)"...

    Quantitative Analysis - Chapter 1- Probabilities - FRM May 2015

    Jayanthi! You did not "bug me" with anything! Please continue to ask questions - it is good for all of us to have an open dialogue. Regarding your question on the 0.75.....this is a very basic concept in integration (or calculus for that matter.) If the exam relied an a significant amount of...

    I mentioned that Bayes example to emphasize that the denomonator should reflect the entire probability space. I hope that makes sense. Brian

    Quantitative Analysis - Chapter 1- Probabilities - FRM May 2015

    Hello Jayanthi. I can't look at the notes at the moment but looking at your questions, I have a couple thoughts. On 1) remember that Bayes says, P(A|B) = P(B|A)•P(A) / (P(B|A)•P(A) + P(B|A')•P(A')) where A' refers to the compliment of A. Regarding EVT, GEV, and GPD, they refer to...

    Quantitative Analysis - Chapter 1- Probabilities - FRM May 2015

    PMF stands for "probability mass function". It is equivalent to PDF, or "probability distribution function", but is specific to discrete distributions. To reiterate, discrete distributions are not typically described as PDFs; rather, discrete distributions are called PMFs whereas continuous...

    Student t distribution

    I would conclude that it is a large number of samples since your question states "sampling" distribution. However, it is an interesting question. If we assume we are dealing with samples only, then what if each sample contains only one observation? Then I am not sure that "large" would be...

    Quantitative Analysis - Chapter 1- Probabilities - FRM May 2015

    Jayanthi, BT does indeed retain material from year to year where they deem it appropriate, particularly when the retained material is fundamental to the FRM program, as is the case with the Chapter you identified. Is it required? Perhaps not! But if you have trouble with the elementary...

    Pro-cyclical effects of VaR-based capital measures

    Thank you @desaiha. If I am understanding you correctly, you are stating that Pro-Cyclical VaR measures would be positively correlated with economic indicators. So, if GDP rises, for instance, which would suggest an improving economy, then a Pro-Cyclical VaR would also rise, thus indicating a...

    Pro-cyclical effects of VaR-based capital measures

    Can anyone help me understand what BIS means when they say "pro-cyclical effects?" I see it referenced numerous times in the Messages from the Academic Literature on Risk Measuring for the Trading Books reading. Thanks Brian

    Practice exam scores!

    Please share your information (if you can) for future test takers! In my studies for Actuarial Exams at The Infinite Actuary, I found it extremely helpful when students would report their practice exam scores and then, after taking the actual exam, report their result. I think this will give us...

    Appendices in Chapter 4 of Dowd

    I have reread these appendices a number of times....I think GARP purposefully places the least interesting readings at the front of the material to weed out the lesser committed! I don't think GARP will ask any specific questions from these appendices....anyone else have any thoughts? Best...

    Spreadsheet illustrating Bootstrap HS

    Thanks Shakti! Are you an employee of BT or simply a fantastic resource? Or both? Regarding my question, I am looking for an example utilizing the bootstrap (and jackknife technique too) if available. I understand the simple HS, but was wondering if the BS of JK techniques are available in...
