WebDec 18, 2024 · Of course it is possible to change $\quad y=a(1-e^{bx}) \quad$ for a linear regression. Don't think that is not possible. The calculus is shown below with a numerical example. Instead of trying to linearize the original function with elementary transform, we use integral transform. WebThe slope of the graph is an answer to this. Remember the linear regression equation? Y = a + bx. In the above equation, the slope is represented by “b”. And the linear regression equation for our example turned out as follows: Y= 612.77 – 19.622x. Here, the value for b is -19.622 and so is our slope.
