    Modeling the Public Transport Networks: A Study of Their Efficiency by Mary Luz Mouronte-López

    Published 2021-01-01
    “…We have found that this process may be appropriately explained by a generalized linear model (GLM) using local, global, and quasilocal similarity indexes as explanatory variables. In modeling, the response variable was described by a binomial probability density function, and the logit function was used as a link function. …”
