BMisc

BMisc includes miscellaneous functions for working with panel data, quantiles, dealing with formulas, among other things.

Installation

You can install BMisc from github with:

# install.packages("devtools")
devtools::install_github("bcallaway11/BMisc")

or from CRAN with:

install.packages("BMisc")

Example 1: Working with distribution functions

The make_dist creates a distribution function from a vector of value of the random variable and the corresponding value of its cdf.

library(BMisc)
y <- rnorm(100)
y <- y[order(y)]
u <- runif(100)
u <- u[order(u)]
F <- make_dist(y, u)
class(F)
#> [1] "ecdf"     "stepfun"  "function"
# plot(F)

Example 2: Working with panel data

Another useful function is the make_balanced_panel function which drops observations from a panel dataset which are not available in all time periods.

id <- rep(seq(1, 100, 1), 2) ## individual ids for setting up a two period panel
t <- rep(seq(1, 2), 100) ## time periods
y <- rnorm(200) ## outcomes
dta <- data.frame(id = id, t = t, y = y) ## make into data frame
dta <- dta[-7, ] ## drop the 7th row from the dataset (which creates an unbalanced panel)
nrow(dta)
#> [1] 199
dta <- make_balanced_panel(dta, idname = "id", tname = "t")
nrow(dta) ## now all the observations with missing data in any period are dropped
#> [1] 198
