| Library: | glm |
| See also: | glmmultlo |
| Quantlet: | glmmultshape | |
| Description: | reshapes data from panel format to matrix format and vice versa. The matrix format is needed for glmmultlo. |
| Usage: | xnew = glmmultshape(x,m,format) | |
| Input: | ||
| x | n x r matrix, the predictor variables. x can be either in matrix format, then r=m*q, i.e. x consists of q nxm matrices. If x is in panel format, n=m*k. | |
| m | number of alternatives. | |
| format | either "panel" or "matrix", the format that the output should have. | |
| Output: | ||
| xnew | reshaped x matrix. | |
