Data: Logarithmic Curve

Using the same data as other curves, we may want to try another model: square root model ( Square Root Curve). To do model transformation, first we need to transform the x values of our data into Square Root Curveso that the transformed model is Square Root Curve. 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 R-squared of 0.9999. The square root model is therefore Square Root Curve
