Statistics for International Large-Scale Assessments (ILSA).

ILSAstats

Calculates point estimates and standard errors using replicate weights and plausible values for International Large-Scale Assessments (ILSA), including: means, proportions, quantiles, correlations, singlelevel regressions, and multilevel regressions.

Installation

You can install the stable version of ILSAstats directly from CRAN:

install.packages("ILSAstats")

Or, if you wish to install the development version of ILSAstats:

remotes::install_github("dopatendo/ILSAstats")

Create replicate weights

Before working with replicate weights statistics we need to be sure to create the replicate weights (if they are not provided within the data). For an example on how to create them see vignette("repweights").

Setup

When doing multiple estimations we may need to use the same options more than one time. For an example on how to create a setup object for ILSAstats see vignette("setup").

Means

For an example on estimating means using replicate weights and plausible values see vignette("means").

Proportions

For an example on estimating proportions using replicate weights and plausible values see vignette("proportions").

Quantiles

For an example on estimating quantiles using replicate weights and plausible values see vignette("quantiles").

Correlations

For an example on estimating correlations using replicate weights and plausible values see vignette("correlations").

League tables

For an example on estimating league tables automatically see vignette("leaguetables").
