Plot for optimal transformation parameter - linear models

Usage

plot_trafolm(lambdarange, lambdaoptim, measoptim, y, x, trafo, method,
  custom_func, custom_func_std)

Arguments

lambdarange

a numeric vector with two elements defining an interval that is used for the estimation of the optimal transformation parameter.

lambdaoptim

optimal or given transformation parameter.

measoptim

measure at the optimal transformation parameter.

y

dependent variable.

x

matrix of regressors

trafo

a character string that selects the transformation.

method

a character string. Different estimation methods can be used for the estimation of the optimal transformation parameter: (i) Maximum likelihood approach ("ml"), (ii) Skewness minimization ("skew"), (iii) Kurtosis optimization ("kurt"), (iv) Divergence minimization by Kolmogorov-Smirnov ("div.ks"), by Cramer-von-Mises ("div.cvm") or by Kullback-Leibler ("div.kl"). Defaults to "ml". In case of no and log transformation "NA" can be selected since no optimization is necessary for these two transformation types.
