Geometric circle fitting with Levenberg-Marquardt (a, b, R), Levenberg-Marquardt reduced (a, b), Landau, Spath and Chernov-Lesort. Algebraic circle fitting with Taubin, Kasa, Pratt and Fitzgibbon-Pilu-Fisher. Geometric ellipse fitting with ellipse LMG (geometric parameters) and conic LMA (algebraic parameters). Algebraic ellipse fitting with Fitzgibbon-Pilu-Fisher and Taubin.

A Parametric Method for Generating Synthetic Data
person("Sidharth", "Macherla", email = "msidharthrasik@gmail.com",
role = c("aut", "cre"), comment = c(ORCID = "0000-0002-4825-2026"))
Builds synthetic data applicable across multiple domains. This package also provides flexibility to control data distribution to make it relevant to many industry examples.

Merges and extends multiple packages and other published scripts calculating Conley (1999) <doi:10.1016/S0304-4076(98)00084-0> standard errors. Details are
available in the function documentation and in the vignette.
