New Version of the R package originally accompanying the paper "Parameterizing celltocell regulatory heterogeneities via stochastic transcriptional profiles" by Sameer S Bajikar, Christiane Fuchs, Andreas Roller, Fabian J Theis and Kevin A Janes (PNAS 2014, 111(5), E626635 <doi:10.1073/pnas.1311647111>). In this paper, we measure expression profiles from small heterogeneous populations of cells, where each cell is assumed to be from a mixture of lognormal distributions. We perform maximum likelihood estimation in order to infer the mixture ratio and the parameters of these lognormal distributions from the cumulated expression measurements. The main difference of this new package version to the previous one is that it is now possible to use different n's, i.e. a dataset where each tissue sample originates from a different number of cells. We used this on phenoseq data, see: Tirier, S.M., Park, J., Preusser, F. et al. Phenoseq  linking visual features and gene expression in 3D cell culture systems. Sci Rep 9, 12367 (2019) <doi:10.1038/s41598019487714>).
