Summary and concluding remarks 1. Introduction Financial econometrics and statistics have become more important for empirical research in both finance and accounting. Asset pricing and corporate finance research have used both econometrics and statistics, such as single equation multiple regression, simultaneous regression, panel data analysis. Portfolio theory and management have used different statistics distributions, such as normal distribution, stable distribution, and log normal distribution. Options and futures have used binomial distribution, log normal distribution, non-central chi square distribution, and so on. Auditing has used sampling technique to determine the sampling error for auditing. The main purpose of this handbook is to review financial econometrics and statistics used in the research of finance and accounting for last five decades. Some suggestions to apply these techniques in future research are also recommended. The second section of this paper will discuss alternative single equation regression estimation methods. Section 3 will discuss simultaneous equation models. Section 4 will discuss panel data analysis. Section 5 will discuss alternative methods to deal with measurement error. Section 6 will discuss time series analysis. Section 7 will discuss spectral Analysis. Section 8 will discuss statistical distribution. Section 9 will discuss principle components and factor analyses. Section 10 will discuss non-parametric, semi-parametric, and GMM analyses. Section 11 will discuss path analysis. Section 12 will discuss cluster analysis. Finally, section 13 will summarize the paper. 2.

Summary and concluding remarks In this paper, we have review both financial econometrics and statistics methods which has been used in finance and accounting research for last four decades. In this handbook, we include research papers in both finance and accounting which present different methodologies in detailed. Therefore, it will be very useful to researcher when they try to perform similar kind of research. References Chang, C.
