3.2 Research method
Multiple linear regressions (MLR) are the method of statistics in regression that used to analyze the relationship
between single response variable (dependent variable) with two or more controlled variables (independent
variables). This method was selected for this research because there were more than controlled variables. In this
research, response variable is marine fish landing ( Y ) while fishermen ( X1 ), fishing boat ( X2 ) and fishing gears
licensed ( X3 ) were controlled variables.
There were four general steps to build forecasting model of fish landing in MLR. The general steps were checking
assumptions, selecting suitable methods of MLR, interpret the output and develop equation of MLR.
