Non Linear Regression: Square Root Curve
Data:
Using the same data as other curves, we may want to try another model: square root model ( ). To do model transformation, first we need to transform the x values of our data into so that the transformed model is . There is no transformation of model parameters in this case.
When we plot sqrt(x) and y, we can obtain almost exact linear model with higher Rsquared of 0.9999. The square root model is therefore
