Estimated Regression Equation(s)
• [name of dependent variable] = [value of coefficient estimate] + [value of coefficient estimate]*[name of 1st independent variable] + [value of coefficient estimate]*[name of 2nd independent variable] + [value of coefficient estimate]*[name of another independent or control variable in the regression model] + [...]
• [if interaction write two separate equations]
Interpret the Regression Results
• The regression coefficient for [1st independent variable] is [/not] statistically significant at the 5 per cent level.
• Controlling for the other variables, a one-unit increase in the [1st independent variable] is associated with a [value of the coefficient estimate] [increase/decrease] in the [name of the dependent variable].
Interpret the Regression Results
• The regression coefficient for [2nd independent variable] is [/not] statistically significant at the 5 per cent level.
• Controlling for the other variables, a one-unit increase in the [2nd independent variable] is associated with a [value of the coefficient estimate] [increase/decrease] in the [name of the dependent variable].
Interpret the Regression Results
• [other interesting findings from the regression, such as changes in the value of adjusted R-square, coefficient estimates for interaction terms and/or for other control variables].
