BinDat: R6 class for storing the design matrix and binary outcome for a single logistic regression
Description
This R6 class can request, store and manage the design matrix Xmat, as well as the binary outcome Bin for the
logistic regression P(Bin|Xmat).
Can also be used for converting data in wide format to long when requested,
e.g., when pooling across binary indicators (fitting one pooled logistic regression model for several indicators)
The class has methods that perform queries to data storage R6 class DatNet.sWsA to get appropriate data columns & row subsets
