0.1-5 (Sep 14, 2026)
  * Added a new method for computing Cook's distance for LAD regression, based on the 
    fitted-value measure proposed by Sun and Wei (2004). Now, function cooks.distances() 
    have the options "L1" and "L2" for 'lad' objects. 
  * The routine leverages.lad() for computing leverage values in LAD regression has been 
    included. This leverage constants are based on the definition proposed by Flores (2015), 
    implemented through an equivalent linear programming formulation.

0.1-4 (Apr 05, 2026)
  * Starting from version 4.6.0 of R, the function hatvalues.nls() will be included in 
    the "stats" package; therefore, it has been removed from india. Please use function
    leverages.nls() instead.
  * Now, function leverages.nls includes the options "tangent" and "jacobian" to compute
    tangent plane leverage (Ross, 1987) and Jacobian leverage (St. Laurent and Cook, 1992). 

0.1-2 (Feb 18, 2026)
  * Added routines to compute randomized quantile residuals for linear regression, 
    ordinary least squares, lad regression, nonlinear least squares and ridge regression.
  * Routines for the computation of QQ-plots with simulated envelope were included.
  * Added the aircraft dataset introduced in Rousseeuw and Leroy (1987, pp. 154).

0.1-1 (May 04, 2025)
  * Added routines to compute leverages, Cook's distances and likelihood displacement 
    for the nonlinear regression model fitted by nls function.

0.1 (Nov 02, 2023)
  * Initial release of india on CRAN.
