I have a simple question for data transformation for fitting my dataset to a negative exponential graph. There are negative values on my dataset which hinder fitting a negative exponential curve. How can I successfully transform my data in statistical way? My data is about Mantel correlation coefficients with distance. Here is my data.
Distance Coefficients 1 0.7241232 2 0.19643728 3 -0.06509062 4 -0.16492022 5 -0.39367865 6 -0.50758682
What is the best way to transform this data?
