5. Interpreting dummy variables for multiple categories when the dependent variable is log(y)Consider the following estimated model, where the dependent variable is the log of the hourly wage:log (wage) 0.417 + 0.297 female + 0.053 married + 0.08 educ + 0.029 exper - 0.001 exper² + 0.032 tenure-0.001 tenure²The coefficient of married implies that the so-called marriage premium is estimated to be aboutSuppose a regression model has different intercepts for seven groups or categories. Then to ensure the quality of the regression model, we need toincludedummy variables in the model,an intercept.

The question is about regression.Given :Dependent variable : log ( wage ).Regression equation :

A standard "money demand" function used by macroeconomists has the form In(m) = Bo + B, In(GDP) + B2R, Where m is the quantity of (real) money, GDP is the value of (real) gross domestic product, and R is the value of the nominal interest rate measured in percent per year. Supposed that B, = 2.15 and B, = -0.06. %3D What is the expected change in m if GDP increases by 3%? The value of m is expected to V by approximately%.

One of the possible models for the coronavirus is the logistic curve, shown here without scale. This curve shows the total number of cases of people infected with the virus. The rate of change for this curve is the number of ca es per day. 1. On the curve, mark the point at which the number of cases per day is greatest. What is a mathematical term for this point? 2. One of the criteria for re-opening activities is fourteen consecutive da s with a decreasing number of cases. Where is this on the curve? Number of Infected people as a function of time
