Moda, media y mediana de la altura del relieve mexicano por Tovar Cabañas, Rodrigo, Jáuregui Díaz, José Alfredo, Vázquez Espinosa, Shany Arely

“…El área estudiada comprende todo el territorio nacional: 1) se trabajó sobre un universo superior a los 9 mil millones de celdas; 2) los 225 m2 que cubre cada celda es la mayor resolución que se ha logrado obtener para la escala nacional; 3) de estas, 58 % cae dentro de un promedio altitudinal de los 1 040 metros sobre el nivel del mar (m. s. n. m.), mientras que el rango 0-100 m. s. n. m. corresponde a la moda, pues dicho intervalo se repite en 18 % de las celdas, en tanto que la mediana ocupa el valor de 1 045; 4) se determinó con un criterio analógico que la pequeña ciudad de Zumpango del Río, Guerrero, se sitúa sobre el promedio altitudinal, en tanto que, territorialmente hablando, la demarcación municipal de Axochiapan, Puebla, presenta el promedio altitudinal de la nación; y 5) respecto a la moda, las localidades de Puerto Vallarta, Jalisco, y Acayucan, Veracruz de Ignacio de la Llave, son una buena representación de dicha tendencia e Ixtlán del Río, Nayarit, con sus 1 044 m. s. n. m., representaría la mediana.…”

Conditional betas and Market re-definition: Revisiting the capital asset pricing model with Mexican data por Treviño Villarreal, María de Lourdes

“…A size effect was also found, although it is not very important. In spite of the empirical support found for the conditional CAPM over the static CAPM, both specifications explain about half of the monthly average return variation, which calls for differences in the pricing of risk between developed and emerging countries…”
