SGP (version 0.9-0.0)

abcSGP: Perform 5 step sequence: prepareSGP, analyzeSGP, combineSGP, summarizeSGP, and visualizeSGP

Description

Utility function to perform sequence of 5 steps going from data preparation, prepareSGP, SGP data analysis, analyzeSGP, data combining, combineSGP, data summarization, summarizeSGP, and data visualization visualizeSGP. Calculating and using student growth percentiles is as easy as ABC.

Arguments

sgp_object

A list containing LONG formatted data. See sgpData_LONG for an exemplar. NOTE: Data preparation must be meticulous to utilize this enhanced functionality.

state

Acronym indicating state associated with the data for access to embedded knot and boundaries, cutscores, CSEMs, and other relevant state level data.

steps

Vector containing all or some subset of prepareSGP, analyzeSGP, combineSGP,

years

A vector indicating year(s) in which to produce student growth percentiles and/or student growth projections/trajectories. If missing the function will use the data to infer the year(s) in which to perform growth percentile analyses based upon the assum

content_areas

A vector indicating content area(s) in which to produce student growth percentiles and/or student growth projections/trajectories. If missing the function will use the data to infer the content area(s) available for analyses.

grades

A vector indicating grades for which to calculate student growth percentiles and/or student growth projections/trajectories. If missing the function will use the data to infer all the grade progressions for student growth percentile and student growth pr

prepareSGP.var.names

list supplied to prepareSGP mapping provided variable names to variable names required as part of the SGP package. See prepareSGP for more details. Defaults to NULL.

sgp.percentiles

Boolean variable indicating whether to calculate student growth percentiles. Defaults to TRUE.

sgp.projections

Boolean variable indicating whether to calculate student growth projections. Defaults to TRUE.

sgp.projections.lagged

Boolean variable indicating whether to calculate lagged student growth projections often used for growth to standard analyses. Defaults to TRUE.

sgp.percentiles.baseline

Boolean variable indicating whether to calculate baseline student growth percentiles and/or coefficient matrices. Defaults to TRUE.

sgp.projections.baseline

Boolean variable indicating whether to calculate baseline student growth projections. Defaults to TRUE.

sgp.projections.lagged.baseline

Boolean variable indicating whether to calculate lagged baseline student growth projections. Defaults to TRUE.

simulate.sgps

Boolean variable indicating whether to simulate SGP values for students based on test-specific Conditional Standard Errors of Measurement (CSEM). Test CSEM data must be available for simulation. Must be set to TRUE for confidence interval construction

parallel.config

A named list with, at a minimum, two elements indicating 1) the BACKEND package to be used for parallel computation and 2) the WORKERS list to specify the number of processors to be used in each major analysis. The BACKEND element can be set = to F

save.intermediate.results

Should intermediate results of abcSGP be saved after each of prepareSGP, analyzeSGP, combineSGP

sgPlot.demo.report

A boolean variable (defaults to FALSE) indicating whether to produce only the demonstration student report catalog. Default is to produce reports for entire current year data.

sgp.summaries

A list giving the summaries requested for each group analyzed based upon the summary.group argument. Default is NULL allowing the summarizeSGP function to produce the list of summaries

summary.groups

A list consisting of 8 types of groups across which all summaries are taken: institution, content, time, institution_type, institution_level, demographic, and instituti

confidence.interval.groups

A subset of the groups provided in the summary.groups argument indicating which groups to provide confidence intervals for. See documentation for summarizeSGP and

plot.types

A character vector passed to visualizeSGP indicating the types of plots to produce. Currently supported plots include bubblePlots,

Value

• Function returns a list containing the input long data set in the Student slot as a data.table keyed using VALID_CASE, CONTENT_AREA, YEAR, ID, SGP results including student growth percentile and student growth projections/trajectories in the SGP slot, and summary results in the Summary slot.

Examples

## Runs all 5 steps
Demonstration_SGP <- abcSGP(sgp_object=sgpData_LONG, state="DEMO")


## Or letting the function detect the state

Demonstration_SGP <- sgpData_LONG
Demonstration_SGP <- abcSGP(Demonstration_SGP)
