gatherData.pred: Convert a dataset without a dependent variable

In jknowles/ModelEWS: Wisconsin Dropout Early Warning System

Description

Convert a dataset without a dependent variable

Usage

gatherData.pred(grade, conn, year, na.omit = TRUE, ...)

Arguments

grade	a numeric representing the grade level to extract data for
conn	a connection object suitable for extracting data
year	a character representing the school year to predict for in YYYY-YYYY format
na.omit	logical, should rows with an NA be omitted, default is TRUE

Details

First the function extracts data from buildTrainingPool, then it builds a model matrix suitable for passing to a transformation and then prediction step. The key difference between this and the original gatherData is that there are no valide dependent variable observations for data we want to make predictions on. This function is modified to account for that.

Note

na.omit must be true for now as no imputation routines have been integrated
