timss.per.pv: TIMSS percentiles

In dickli/intsvy2: International Assessment Data Manager 2

Description

Calculates percentiles for plausible values

Usage

  timss.per.pv(pvlabel="BSMMAT", by, per, data, export=FALSE, name= "output", 
  folder=getwd())

Arguments

pvlabel	The label corresponding to the achievement variable, for example, "BSMMAT", for overall mathematics performance.
per	User-defined percentiles (e.g., per = c(5, 10, 25, 75, 90, 95)).
by	The label of the categorical grouping variable (e.g., by="IDCNTRYL") or variables (e.g., by=c("IDCNTRYL", "ITSEX")).
data	An R object, normally a data frame, containing the data from TIMSS.
export	A logical value. If TRUE, the output is exported to a file in comma-separated value format (.csv) that can be opened from LibreOffice or Excel.
name	The name of the exported file.
folder	The folder where the exported file is located.

Value

timss.per.pv returns a data frame with percentiles and associated standard errors. Default weights (e.g. "TOTWGT" in TIMSS) and percentiles are specified in the config parameter.
