Two sectors of some economy are Sector 1 and Sector 2. The input-output table involving these two sectors results in the following value for (I-A), where

One of the key tasks in metropolitan area transportation planning is to estimate the total number of trips made by households during a typical day. The dependent variable is the number of trips made by a household per day, known as the trip generation rate. One of the most important determinants of variations in household trip generation rates is household income. Consider a hypothetical city, values of the trip generation rates and household income are listed in the following table.    (a) Find the regression coefficients (the intercept and the slope coefficients). Interpret the meaning of the slope coefficient.(b) Write out the regression line formula.(c) Calculate the coefficient of determination for this problem.

Suppose you believe that population abundance (A) of a particular species is a linear function of vegetation coverage (V) and the presence of a predators (P). Surveys where conducted across 20 sites and found the following information: a) There was an average of cover of .406 (40.6%) of the area, with an average 6.8 predators and 61.55 individuals in our target population. b) ⟨V2⟩=0.231⟨V2⟩=0.231, ⟨P2⟩=76.300⟨P2⟩=76.300, ⟨VP⟩=2.933⟨VP⟩=2.933, ⟨VA⟩=36.329⟨VA⟩=36.329, ⟨PA⟩=379.300⟨PA⟩=379.300 Set up the appropriate system of equations needed for a the linear regression of a model of the form A=aV+bP+cA=aV+bP+c. Then estimate the parameters and report the final model.
