This paper, through comparing the determinants between corporate failures and survivors, identifies factors in relation to liability of newness that cause corporate failures. Liability of newness has attracted research attention as a significant attribute for organizational failure, in...

In a healthcare system, resource allocation mechanisms should promote efficiency, improve quality of care and reduce practice variation. This paper presents a framework that has been used at the US Department of Veterans Affairs, VA Healthcare Network Upstate New York, to guide resource...

We propose two tests for the equality of covariance matrices between two high-dimensional populations. One test is on the whole variance-covariance matrices, and the other is on offdiagonal sub-matrices which define the covariance between two non-overlapping segments of the high-dimensional...

We study two tests for the equality of two population mean vectors under high dimensionality and column-wise dependence by thresholding. They are designed for better power performance when the mean vectors of two populations differ only in sparsely populated coordinates. The first test is...
