问题 I'm migrating from Stata to R ( plm package ) in order to do panel model econometrics. In Stata, panel models such as random effects usually report the within, between and overall R-squared. I have found that the reported R-squared in the plm Random Effects models corresponds to the within R squared. So, is there any way to get the overall and between R-squared using the plm package in R? See same example with R and Stata: library(plm) library(foreign) # read Stata files download.file('http:/

问题 I am having difficulty converting a vector of integers into dates. I've imported a dataset from Stata using: > dataire <- read.dta13("~/lcapm_ireland.dta", convert.factors = TRUE, generate.factors = FALSE, encoding = "UTF-8", fromEncoding = NULL, convert.underscore = FALSE, missing.type = FALSE, convert.dates = TRUE, replace.strl = TRUE, add.rownames = FALSE) My date variable is a monthly time series starting on January 2000 and formatted as "2000-Jan". Similarly to R, Stata handles dates as
