    Course Study Plan Guide

    I also purchased the Schweser notes before purchasing BT's product as I assumed they would be better (by default) given their domination with the CFA. I couldn't have been more wrong - the schweser product is terrible for the FRM! Absolutely terrible. Just keep preparing with the BT...

    E/CTRM Systems Career Trajectory with FRM?

    I agree with Shakti. While it is true that simple math is predominant, there is some higher level statistics throughout, which I would argue is math at the end of the day. Still, it is limited.

    Course Study Plan Guide

    I passed 1 with 2112 (if I remember correctly) and I used the following approach. I might add that I take a very long time to prepare as I have 2 very young children (4 and 1). Hence, I am still preparing for part II but I am using the same approach. 1) Reach original reading. 2) Watch...

    I am hoping this doesn't come across the wrong way.....I am happy for @blazei I feel like passing someone with 44411 is a disservice to the credential.

    I would try to be conscientious about recruiting partners to study away from this forum - I am not suggesting that you are doing that.....which is why I asked. I wouldn't want someone to be poaching from this site to benefit another or at the expense of BT. ...my two cents.

    Partial autocorrelation

    Hi @David Harper CFA FRM I am a bit confused by the description that partial autocorrelation function as the coefficient if the most distant term after regressing the current in the past series. Don't we have only one series here, and therefore, only 1 sample point for each independent...

    Defining Parameters

    This is a very imprecise post - I'd be happy to offer my thoughts (and I am sure everyone else would be too) if you could be a bit more specific.

    Omitted Variable Bias

    I could go on and on on this topic.....but I think we have beaten it to death! Thanks everyone, especially @ShaktiRathore and @ami44.

    Alas - I see. Indeed you are a genius @ShaktiRathore ....that makes sense now. Thank you!

    Omitted Variable Bias

    I don't follow how Z is a linear function of X1 and X2 - I must be missing something obvious.

    Omitted Variable Bias

    While I appreciate your response @ShaktiRathore, I am having a hard time understanding it. Are you saying Z is a linear function of X1 and X2?

    CAPM and return on asset

    The CAPM says that the expected return on an asset E(R) is equal to the risk free rate + Beta*(Market Return minus the risk free rate) OR E(R) = risk free rate + Beta*(Market Risk Premium). Let Risk Free Rate = X and Market Risk PRemium = Y. Then we have 2 equations and 2 unknowns, as below...

    Omitted Variable Bias

    Here is my question, to reiterate. Let Y = Xo + B1X1 + B2X2 + u. Then, assume Z = X2^2 (or X2^3 or any other nonlinear relationship, like Z = sqrt(X2), etc.) AND assume that Z is a determinant of Y. Then, is there there OVB? We have that Y is dependent on Z which is one of the...
