Application of linear regression in analysis of Tabriz annual temperature trend

Regression methods are most applied technique in trend analysis. The most recent research paid more attention to parametric methods; however, there are many techniques to analyze regression. In this paper, three methods of linear regression have introduced and applied to Tabriz temperature based on assumpation of its linearity in behavior. So parametric, non-parametric and Byas regression have fitted to annual temperature of Tabriz. The best regression model have chosen based on t-statistic, precision, deterministic, obviously and residual tests. Based on non-parametric method annual temperature trend of Tabriz has on interval of 0.03- 0.04 degree centigrade per year.
