Geometrically, the linear constraints define the feasible region, which is a convex polyhedron. A linear function is a convex function, which implies that every local minimum is a global minimum; similarly, a linear function is a concave function, which implies that every local maximum is a global maximum. An optimal solution need not exist, for two reasons. First, if the constraints are inconsistent, the… Nettet27. jan. 2024 · 2 Answers. import statsmodels import statsmodels.api as sm import numpy as np # Set the link function to identity statsmodels.genmod.families.links.identity () OLS_from_GLM = sm.GLM (y, sm.add_constant (np.column_stack (x, z))) '''Setting the restrictions on parameters in the form of (R, q), where R and q are constraints' matrix …

If you pass beq as a row vector, solvers internally convert beq to the column vector beq(:). For large problems, pass beq as a sparse vector. beq encodes the Me linear equalities.
