With the release of Stata 7, the glm command for fitting generalized linear models underwent a substantial overhaul. Stata 7 glm contains an expanded array of variance estimators, regression diagnostics, and other enhancements. The overhaul took place to coincide with the release of Hardin and Hilbe (2001). With the new glm came a modular design that enables users to program customized link functions, variance functions, and weight functions to be used if Newey-West covariance estimates are desired. Because cases requiring customized link functions are the more prevalent in the literature, only those are considered here. We give two examples where a nonstandard link function is required: the relative survival model of Hakulinen and Tenkanen (1987) and a... |

La presión por el uso de la tierra en México, ha provocado que en la superficie terrestre del país se presente algún nivel de degradación. Los principales procesos causales de la degradación de los suelos en México son la erosión hídrica y eólica, para contrarrestar esta problemática, el gobierno federal promueve estrategias de conservación y manejo sustentables de los suelos; para ello, las dependencias del gobierno realizan estas actividades con metodologías propias y dispersas para programar acciones, diseños, cálculos, y construcción, con sus respectivos conceptos de gastos. Por ello, y con el propósito de apoyar a los operadores de los programas de conservación de suelo y agua, se realizó este trabajo que consistió en la concepción y desarrollo de... |

Early weaning (EW) leads to overweight, visceral obesity, hyperleptinemia, and insulin resistance in adulthood. Treatment with Ilex paraguariensis (yerba mate) improves obesity and insulin resistance in these animals. Here, we evaluated the effects of chronic treatment with yerba mate on the redox balance and liver morphology of overweight early-weaned rats. To induce EW, we wrapped the dams with bandages to interrupt milk access during the last 3 days of lactation. Control pups (C) had free access to maternal milk for the full 21 days of lactation. On postnatal day (PN) 150, EW offspring were subdivided into the EW+YM group, which received the aqueous extract of yerba mate (1 g/kg bw by gavage once a day for 30 days) and the EW group, which received water... |
