Output Regression Type

Set the regression type. Three types are available:

• Linear Regression: find a straight line in the form of y = a.x + b, where a is the slope and b is the intercept that best fits the data.

• Logarithmic regression: find a logarithmic curve in the form of y = a.ln(x) + b, where a is the slope, b is the intercept and ln(x) is the natural logarithm of x, that best fits the data.

• Regressió potencial: troba una corba de potència de la forma a.x^b, on a és el coeficient i b és la potència que s'ajusta millor a les dades.

The results of the three types of regression analysis of the measurements in the table above are shown below.
