Consequently, this essay choose the "Z-Score Model", which was developed by Altaian, the famous American expert in risks management, to analyze and evaluate the listed companies' credit risks in China and to verify its efficiency to Chinese stocks market. The " Z-Score Model" is an innovation in the evaluation of companies' credit risk in the United States' banks, which is now being used widely. If the model is also applicable in Chinese stocks market, it will be significant in both theories and practices.

For separable and continous exponential family models (such as normal, gamma, and inverse Gaussian models), this paper discusses the tests for departures from nominal dispersion in the framework of longitudinal nonlinear models with varying dispersion and/or random effects. The score test statistics are constructed and their asymptotic distributions and local powers are derived.

The difference between codon choice randomization in the region of protein regular secondary structure and that in coil region is investigated in detail. We find that the folding free energy of mRNA segments in different protein secondary structures is significantly different. The average Z score is -1. 38 and -1. 71 for regular secondary structure, but -0.93 and -1. 03 for coil.
