发帖数: 9020 | 4 For modern systems, wear estimation plays an important role
in preventing failure, scheduling maintenance, and improving
utility. Wear estimation relies on a series of sensors, measuring the state
of the system. In some components, the sensors
used to estimate wear may not be fast enough to capture brief
transient states that are indicative of wear. For this reason
it is beneficial to be capable of detecting and estimating the
extent of component wear using steady-state measurements.

of $0.50 earning per share. XYZ is traded at $50 per share.
Now, analysts suddenly find that they need to revise their
estimates. The updated average EPS is $0.60.
What will be the result?
Is the market efficient enough to price in that change immediately?
XYZ should rise because of that. Because originally, it is likely
to beat the estimate. Now after the revision, it may lose to the

Question 2: With this new estimate, what the best approach to re-direct the

发帖数: 7 | 38 My opinions:
Q1. Since your estimate is based on history of sensor readings, the best
approach is probably Maximum a Posteriori (MAP) estimate.
Q2. Maximum likelihood estimation (MLE) is very helpful and it picks the
values of the model parameters that make the data more likely than any other
values. MLE can be used to estimate the new location of sensors.
