Approximate Maximum Likelihood Commercial Bank Loan Management Model

Market concentration and commercial bank loan portfolios

This paper estimates the relationship between banking market concentration and high-risk portfolio strategies at commercial banks. I use the unprecedented changes in the degree of competition in local banking markets that occurred after 1980 to estimate the impact of market competition on the risk profile of commercial bank lending. I find evidence that increasing concentration has been associa...

Approximate Profile Maximum Likelihood

We propose an efficient algorithm for approximate computation of the profile maximum likelihood (PML), a variant of maximum likelihood maximizing the probability of observing a sufficient statistic rather than the empirical sample. The PML has appealing theoretical properties, but is difficult to compute exactly. Inspired by observations gleaned from exactly solvable cases, we look for an appro...

Approximate Maximum Likelihood Sequence Detection

The problem of multiuser detection in asynchronous Direct-Sequence Code-Division Multiple-Access systems with residual errors in timing and amplitude estimation is addressed. Prior work has shown that the maximum-likelihood (ML) solution is sensitive to timing errors as small as a fraction of a chip period. In this paper, residual errors in both synchronization and fading coeecient estimation a...

Approximate Maximum Likelihood Method for Frequency Estimation

A frequency can be estimated by few Discrete Fourier Transform (DFT) coefficients, see Rife and Vincent (1970), Quinn (1994, 1997). This approach is computationally efficient. However, the statistical efficiency of the estimator depends on the location of the frequency. In this paper, we explain this approach from a point of view of an Approximate Maximum Likelihood (AML) method. Then we enhanc...
