TRANFORMATIONS IN REGRESSION We have enriched the properties of the data transformations of the Yeo and Johnson (2000) for negative and positive responses, which we introduced in R2020a. More specifically, we intervened on the smoothness condition that the second derivative of zYJ(lambda) with respect to y be smooth at y = 0, along Atkinson et al (2019) and (2020), to allow two values of the transformations parameter: lambdaN for negative observations and lambdaP for non-negative ones. Now, function ScoreYJall computes: 1) a global t test associated with the constructed variable for lambda=lambdaP=lambdaN. 2) a t test for positive observations. 3) a t test for negative observations. 4) a F test for the joint presence of the two constructed variables described in points 2) and 3. 5) the F test based on the maximum liklihood estimate of lambdaP and lambdaNNew function ScoreYJall which computes the score tests described in points 1)-5) above. New function scoreYJmle which computes, in the case of extended Yeo and Johnson transformation, the likelihood ratio test of H0: lamabdaP=lamabdaP0 and lamabdaN=lambdaNeg0.

In function MixSim optional input structure sph now can be called with field sph.exactrestriction In function tclust the
fourth input restrfactor can be a structure which can contain the

November 2017 Release 2017b.
| Major statistical release. Highlights:
FSDA has introduced two new categories of tools, one for (robust) time series analysis; another for analyzing categorical data and contingency tables. More precisely: (1) Function
LTSts extends LTS estimator to time series. A related new graphical plot associated to a time series,
wedgeplot, provides information on the presence of outliers and level shifts. (2) CorAna performs correspondence analysis; SparseTableTest computes independence test for large and sparse contingency tables; CressieRead computes the power divergence family of tests, to check the discrepancy/distance between observed and expected frequencies in a contingency table; rcontFS generates a random two-way table with given marginal totals; barnardtest computes the Barnard test, corrNominal measures strength of association between two unordered (nominal) categorical variables. Similarly for ordinal data with corrOrdinal. crosstab2datamatrix recreates the original data matrix X from contingency table N. This group of functions is complemented by file examples_categorical.m as in style of FSDA. The two categories of functions will be progressively enriched. Other new functions which are included are boxtest (test of equality of covariance matrices used for example in tkmeans), GYfilt (Gervini and Yohai, univariate outlier identifier), mmdrsplot (interactive plot of the trajectories of minimum Mahalanobis distances from different starting points), overlapmap to plot the ordered pairwise overlap values between components, dempk to perform a merging of components found by tkmeans, ncpci to compute a non centrality parameter confidence interval. Finally, spmplot has been enriched to superimpose ellipses, density and contour functions to data and extract single panels from the scatter matrix. |
