robjhyndman.com пишет про новый R пакет прогнозирования как бе, но пишет следующим образом:
The accuracy function now works with both time series forecasts and cross-sectional forecasts.
то-есть, по-руски прогнозирование -- это предвидение по времени, а попе н достансге -- совсем не обязательно и вводит нас (если на демографическом образовании строицо) в мир indirect techniques

Multivariate regression analysis using categorical explanatory variables
LinkedIN начал новую нитку с этой назвой
Which package is useful to handle categorical variables in a multivariate regression analyisis and where may I find the tutorials? Every information that I find is about quantitative data.
I am currently using a lm function to find the best predictor for a quantitative response variable but I am afraid, it is not the best approach. I also do not want to use dummies.
