A practical method to account for outliers in simple linear regression using the median of slopes [PDF]

open access: yesScientia Agricola, 2023
The ordinary least squares (OLS) can be affected by errors associated with heteroscedasticity and outliers, and extreme points can influence the regression parameters. Methods based on the median rather than on the mean and variance are more resistant to

Robust functional principal components: A projection-pursuit approach [PDF]

open access: yes, 2011
In many situations, data are recorded over a period of time and may be regarded as realizations of a stochastic process. In this paper, robust estimators for the principal components are considered by adapting the projection pursuit approach to the ...
