You are given a set of data (xj, Yi) for linear regression analysis and find out these data are not linearly related by plotting (x¡, Yi) with graphical analysis. After using log transformation of data from (x¡ , yi) to (X¡ = log X¡ , Y¡ = log yi ) and a linear fitting line were derived, Y = A + BX, for the power-law relationship y = k x". You tried to find the power-law equation's kand n by transforming back from A and B in that linear relation equation Y = A + BX. Which one of the below can be the correct result? There might be more than one correct answer; please select all of the correct answers. O logA=k O n= logB O 10A=K O en=B n = B O A=logK O eK=A O eB=n
The percentage of female high school graduates who enrolled in college is given in the table below. College Enrollme Year for Females 1970 25.5 1980 30.3 1990 38.3 2000 45.6 2010 50.5 Let xx represent time (in years) since 1970, and let y represent the corresponding percentage of female high school graduates who enrolled in college. Find the cubic regression model y=F(x)=ax^3+bx^2+cx+d where aa is rounded to 6 decimal places, bb is rounded to 4 decimal places, cc is rounded to 3 decimal places, and dd is rounded to 1 decimal place.
Early in the twentieth century, an intelligence test called the Stanford-Binet Test (more commonly known as the IQ test) was developed. In this test, an individual’s mental age M is divided by the individual’s chronological age C and then the quotient is multiplied by 100. The result is the individual’s IQ. IQ(M, C) = M C × 100 Find the partial derivatives of IQ with respect to M and with respect to C. Evaluate the partial derivatives at the point (12, 10) and interpret the result.

Exercise 4 In this regression we presented the results of the consumption fitted to the income in the period 1980-2005. We divide the data in two periods as 1980-1992 and 1993-2005. Decide if there is a structural change in the consumption-income regression in the two periods. The results for all data are as follows cons = 179 + 0.85 Income RSSfull = 265277 The results for 1980-1992(1) and 1993-2005 (2) are as follows 143 - 0.85 Income RSSfull = 13310 (1) cons = cons = 110 + 0.18 Income RSSfui = 163505 (2) fll
