Testing for change in mean of heteroskedastic time series [PDF]

In this paper we consider a Lagrange Multiplier-type test (LM) to detect change in the mean of time series with heteroskedasticity of unknown form. We derive the limiting distribution under the null, and prove the consistency of the test against the ...

On relation between the power mean and the logarithmic mean

, 2010
碩士假設x及y是不同的正數，則 Mp = Mp (x , y) 稱冪平均數， L = L (x , y) 稱對數平均數。 Chang[2]已證明 : 在某些限制下的x和y，當q0，Mp < L 。 我們將證明在某些限制下的x和y，當q 0，L > Mp。If x , y are distinct positive numbers, then Mp= Mp (x , y) is called the power mean of x and y .

Reliability Analysis Considering the PFC Function and Redundancy Effect of the Vienna Converter

IEEE Access
This paper analyzes the impact of power factor correction (PFC) on the failure rate of a Vienna converter through reliability analysis under conditions where AC-to-DC conversion is possible but the PFC function is not functioning due to a partial failure

Applying Mean-field Approximation to Continuous Time Markov Chains [PDF]

, 2013
The mean-field analysis technique is used to perform analysis of a systems with a large number of components to determine the emergent deterministic behaviour and how this behaviour modifies when its parameters are perturbed.

Explaining bank failures: deposit insurance, regulation, and efficiency [PDF]

This paper uses micro-level historical data to examine the causes of bank failure. For state charactered Kansas banks during 19 10-28, time-to-failure is explicitly modeled using a proportional hazards framework. In addition to standard financial ratios,
