meta
(Package: gamlss.data) :
A Meta Analysis on Smoking Cessation
The data here are coming from a statistical meta analysis problem. In meta analysis we combine the evidence from different studies to obtain an overall treatment effect. The data from Silagy et al. (2003) consist of different clinical trials of nicotine replacement therapy for smoking cessation. In each trial the patient was randomized into a treatment or control group. The treatment group were given a nicotine gum. In the majority of studies the control group receive the same appearance gum but without the ingredients but in some they were given no gum. The outcome, whether the participant is smoking or not, was observed after six months. The data were previously analysed by Aitkin (1999) and by Skrondal and Rabe-Hesketh (2004).

acidity
(Package: gamlss.data) :
The Acidity Data files for GAMLSS
The data shows the acidity index for 155 lakes in the Northeastern United States (previously analysed as a mixture of gaussian distributions on the log scale by Crawford et al.(1992, 1994)). These 155 observations are the log acidity indices for the lakes.

tensile
(Package: gamlss.data) :
The Tensile Data files for GAMLSS
tensile: These data come from Quesenberry and Hales (1980) and were also reproduced in Hand et al. (1994), data set 180, page 140. They contain measurements of tensile strength of polyester fibres and the authors were trying to check if they were consistent with the lognormal distribution. According to Hand et al. (1994) "these data follow from a preliminary transformation. If the lognormal hypothesis is correct, these data should have been uniformly distributed".

margolin
(Package: gamlss.data) :
The Margolin Data files for GAMLSS
margolin: Margolin et al. (1981) present data from an Ames Salmonella assay, where y is the number of revertant colonies observed on a plate given a dose y of quinoline. The data were subsequently analysed by Breslow (1984), Lawless (1987) and Saha and Paul (2005).

The data set, kinkly provided to us by Dr Maria Durban, is based on a study conducted at Harvard University with girls afected by Acute lymphoblastic leukaemia. The obesity and short stature are common effcts on teens who have or have had the disease, and the treatments applied trying to minimize this type of side effects without compromising its effctiveness. In one of the clinical trials conducted, 618 children were studied between the years 1987 and 1995 and three diffrent treatments were applied: intracranial therapy without radiation, conventional intracranial radiation therapy and intracranial radiation therapy twice a day. Approximately every 6 months the children height was measured. For children the height increases smoothly along the years. In this example, (the data have been changed for confidentiality) 197 girls diagnosed with Acute lymphoblastic leukaemia between 2 and 9 years old are measured. The height of the children was measured at different times and in total 1988 observations were collected. The number of observations per child varies between 1 and 21.

A survey was conducted in April 1993 by Infratest Sozialforschung. A random sample of accommodation with new tenancy agreements or increases of rents within the last four years in Munich was selected including: i) single rooms, ii) small apartments, iii) flats, iv) two-family houses. Accommodation subject to price control rents, one family houses and special houses, such as penthouses, were excluded because they are rather different from the rest and are considered a separate market. For the purpose of this study, 1967 observations of the variables listed below were used, i.e. the rent response variable R followed by the explanatory variables found to be appropriate for a regression analysis approach by Fahrmeir et al. (1994, 1995):
