... 1.A power model has the form y = axp, where a and p are constants. 2.Take the logarithm of both sides of this equation. Using properties of logarithms, log y = log(axp) = log a + log(xp) = log a + p log x The equation log y = log a + p log x shows that taking the logarithm of both variables results ...

... Want to predict the assessed value of a house in Ames. Select a random sample of n houses and estimate the population mean of assessed value (using methods in Ch. 7) and use it for prediction. A better method uses other information about the houses used by the assessor (e.g.,sq.ft. of oor space, ...
