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 03, 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.
