Fitting the Emax Model in R Kristian Brock

WebThe equation is: Y = b 0 + b 1 X + b 2 X 2. where b 0 is the value of Y when X = 0, while b 1 and b 2, taken separately, lack a clear biological meaning. However, it is useful to consider that the first derivative is: D (expression (a + b*X + c*X^2), "X") ## b + c * (2 * X) which measures the increase/decrease in Y for a unit-increase in X.
