Yes. No need to do a MPhil then PhD. MPhil means nothing if you had a PhD.

I don’t think you can updraft a MPhil to a PhD at a different university. It only happens within the same uni you’re doing your MPhil as far as I know.
所以我地係price bond option嘅時候根本唔需要理interest rate係乜
我地只需要知道at time t嘅bond price就夠
所以你都可以咁理解 我地係pricing bond option without interest rate

但係解決咗一個問題 另一個更加難搞嘅問題又出現
:^(
:^(
我地整走個discount factor嗰時 同時帶多咗個exponential term入去expectation裡面
而難搞嘅地方在於呢個exponent同佢後面嘅maximum function唔係independent
所以我地冇得用 E ( AB ) = E ( A ) * E ( B ) 呢招
:^(
:^(
等我用下圖簡化少少依家嘅情況同問題
:^(
:^(
依家我地最大嘅問題就係唔識evaluate呢種exponential * maximum function嘅expectation
如果我地可以揾到一種非常神奇嘅方法
