MixAll: Clustering Mixed data with Missing Values

The Clustering project is a part of the STK++ library (Iovleff 2012) that can be accessed from R (R Development Core Team 2013) using the MixAll package. It is possible to cluster Gaussian, gamma, categorical, Poisson, kernel mixture models or a combination of these models in case of mixed data. Moreover, if there is missing values in the original data set, these missing values will be imputed ...

The use of MIXED models in the analysis of animal experiments with repeated measures data

Wang, Z. and Goonewardene, L. A. 2004. The use of MIXED models in the analysis of animal experiments with repeated measures data. Can. J. Anim. Sci. 84: 1–11. The analysis of data containing repeated observations measured on animals (experimental unit) allocated to different treatments over time is a common design in animal science. Conventionally, repeated measures data were either analyzed as...

Comparing the SAS GLM and MIXED Procedures for Repeated Measures

Repeated measures analyses in the SAS GLM procedure involve the traditional univariate and multivariate approaches. The SAS MIXED procedure employs a more general covariance structure approach. This paper compares the two procedures and helps you understand their methodologies. A numerical example illustrates many of the key similarities and differences.

Mixed models for longitudinal left-censored repeated measures

Longitudinal studies could be complicated by left-censored repeated measures. For example, in Human Immunodeficiency Virus infection, there is a detection limit of the assay used to quantify the plasma viral load. Simple imputation of the limit of the detection or of half of this limit for left-censored measures biases estimations and their standard errors. In this paper, we review two likeliho...

Semiparametric Mixed Models for Nested Repeated Measures Applied to Ambulatory Blood Pressure Monitoring Data.

Semiparametric mixed models are increasingly popular for statistical analysis of medical device studies in which long sequences of repeated measurements are recorded. Monitoring these sequences at different periods over time on the same individual, such as before and after an intervention, results in nested repeated measures (NRM). Covariance models to account for NRM and simultaneously address...
