SD_cutoff: Identification of Careless Response Using Standard Deviation

In manateelab/EMAeval-R-Package: Identification of Careless Responses and Responders in EMA Data

Description

SD_cutoff returns dataframe of assessment flagged by Standard Deviation per assessment cutoff value.

Usage

SD_cutoff(data, cutoff, condition, item.colnames, ID.colname)

Arguments

data	dataframe to be analyzed.
cutoff	numeric cutoff value for Standard Deviation, 'default' value set to 5.
condition	character string of condition that is desired for comparison of data to SD cutoff value, i.e <, >=, etc. 'Default' logic set to "<=".
item.colnames	vector of column names of all items/questions to be used to calculate item score Standard Deviation and Longstring responses.
ID.colname	character string of column name for ID of assessment.

Details

This function creates the dataframe that includes the ID and index of assessments that met the cutoff criterion for Standard Deviation per assessment. If an assessment has a Standard Deviation less than or equal to the cutoff value, it will be flagged and placed in the dataframe.

Value

The item "item.colnames" must be the column names of all items to be included in the calculations for Item Score Standard Deviation. The base function colnames can be utilized if user prefers. If columns x through y are to be used for this calculation, the following syntax must be followed: item.colnames = colnames(data[,x:y]) Example of use with column names can bee seen below.
