Logarithmic regression calculator
An exponnetial. e general form of an exponential function is y = abx. Use the regression calculator to find the values of a and b for the water lily population growth. Round to the nearest thousandth. A= 3.915. B= 1.106. The graph to the right shows what you should have gotten on the regression calculator.The fitted (or estimated) regression equation is Log(Value) = 3.03 – 0.2 Age The intercept is pretty easy to figure out. It gives the estimated value of the response (now on a log scale) when the age is zero. We would estimate the value of a “new” Accord (foolish using only data from used Accords) as Log(Value for Age=0) = 3.03Log of Odds = log (p/ (1-P)) This is nothing but the logit function. Fig 3: Logit Function heads to infinity as p approaches 1 and towards negative infinity as it approaches 0. Note: Probability ...
