For the Powder Cocaine Stigmatization regression equation in Table 3,a. Interpret the parameter estimate for Age 20-22b. Interpret the parameter estimate for Hispanic/Latino

For the response variable, y which is Powder Cocaine Stigmatization, the predictors are assumed as Age 20-22 and Hispanic/Latino.The value of estimated regression coefficient for Age 20-22 and Powder Cocaine Stigmatization is given as:The value of estimated regression coefficient for Hispanic/Latino and Powder Cocaine Stigmatization is given as:The given results can be interpreted as for unit increase(decrease) in the Age 20-22, the Powder Cocaine Stigmatization will be decreased(increased) by 0.12.Concept: The regression coefficient is interpreted as for unit change in the independent variable, the proportion equivalent to the regression coefficient will be the amount of change in the dependent variable.The positive sign of the regression coefficient shows that both the variables change in the same direction, i.e. either both increases or decreases.The negative sign of the regression coefficient shows that both the variables changes in the opposite direction(when one iccreases, other decreases and vice-versa).The parameter estimate of Hispanic/Latino can be interpreted as for unit increase(decrease) in the value of Hispanic/Latino, the Powder Cocaine Stigmatization will be decreased(increased) by 0.11.The parameter estimate of the age 20-22 can be interpreted as for unit increase(decrease) in the Age 20-22, the Powder Cocaine Stigmatization will be decreased(increased) by 0.12.The parameter estimate of Hispanic/Latino can be interpreted as for unit increase(decrease) in the value of Hispanic/Latino, the Powder Cocaine Stigmatization will be decreased(increased) by 0.11.
