Hola compañeros de la lista. Tengo el análisis que muestro abajo, para la estimación de la Dosis Letal Media (DL50) por medio de regresión logística, de dos compuestos similares (denominados 1 y 2) aplicados a grupos de individuos similares, evaluando el número de individuos vivos y muertos al final del ensayo. Mi duda es qué forma me recomiendan para determinar si la diferencia es significativa entre las DL50's estimadas para cada compuesto. De antemano muchas gracias por su ayuda. ---------------------------------------------------------------------- Código:...

There are plenty of using kobject_del() and kobject_put() together in the kernel tree. This patch wraps these two calls in a single helper.

Hi, I used subset command, like this: grupoP = subset(dados, grupos=='P', select=c(mortos, vivos, doses, percevejos, p)) and the variables in select option are numeric. I tried fit a model with command: ajuste.logit = glm(cbind(mortos,percevejos)~log10(doses), family=binomial(logit), data=grupoP) and the output is: > ajuste.logit = glm(cbind(mortos,percevejos)~log10(doses), > fa...

Hola buenos días, me presento, me llamo Miguel y 'soy de' y 'vivo en' Galicia. Soy profesor de secundaria (Bachillerato Adultos) y llevo 15 días estudiando R a un buen ritmo, pero todavía me faltan miles de cosas. He visto que R facilita, no solo el análisis de datos y que posee una potencia en cálculos estadísticos a cualquier nivel, sino gran caudal de rec...
