![]() ![]() As often as I use LINEST, I still need to look up it up every time! If you consult a table in a statistics manual, you will find that t-critical, two tailed, with 6 degrees of freedom and Alpha = 0.05 is 2.447. I am interested in working with MS Excel. I will also use Functions to find Coefficient a and Coefficient b for the dataset to see if they match the trendline equation. Here, I will use the exponential trendline equation to find Coefficient a and Coefficient b. You can then compare the predicted values with the actual values. ![]() In the following Image, you can see that from the power trendline equation I have got Constant a and Constant b. After that, you will see that you have got your desired trendline. ![]() In CP/M, how did a program know when to load a particular overlay? In this first example, I will explain how to add a trendline equation in Excel. Michel asks how to get the chart trendline coefficients from the chart into the grid. To do this, follow these steps: Still need help? Refer to the quick reference above for how to generate coefficients for different trend/regression types. Collinearity should be relatively rare in practice. Now, I will use Functions to find Constant a and Constant b for the dataset. ![]()
