Model fit — goal?
Choose the model that best describes data, minimizing errors.
Point cloud — representation?
A set of spatial data points in 2D or 3D space.
Curve fitting — methods?
Using models like linear, polynomial, logarithmic, or exponential to approximate data.
Model fit — goal?
Minimize distance between model and data points.
Scatter plot — purpose?
Visualize data distribution and relationships.
R² — what?
Proportion of variance explained by model.
Affine model — form?
y = a + bx.
Polynomial model — degree?
Degree 2, 3, etc.
Logarithmic fit — formula?
y = log(a x) + b.
Interpolation — definition?
Estimate within data range.
