Do affine transformations preserve convexity?

We show that the parameters of the model can be estimated in a simple and robust manner using survey-like information; and that the model we propose affords a ... constraint on the affine control policy. In what follows, we provide convex ... Y in the form of sparsity constraints (that reflect the pattern of informational ... Error messages, warnings, and informational messages ... HEAD files are actually used. -matvec mmm = Read an affine transformation matrix-vector from file We adopt an affine information structure: Random vector {θi εi}i∈I is ... informational efficiency. Our result complements the aggregation prediction. Mar 27, 2025 ... (relative to the full-information benchmark) under any symmetric profile of affine demand schedules.
