Apply top or bottom coding with log IQR — transform_top_code_with

Applies an upper or lower limit on variable values using the Interquartile Range (IQR) of the variable transformed with the natural logarithm and a scale factor ('times').

Usage

transform_top_code_with_iqr(
  lissy_files,
  variable,
  times = 3,
  files_level = NULL,
  variable_level = NULL,
  weight = NULL
)

transform_bottom_code_with_iqr(
  lissy_files,
  variable,
  times = 3,
  files_level = NULL,
  variable_level = NULL,
  weight = NULL
)

Arguments

lissy_files: A list of LIS or LWS files.
variable: A character string with the name of the variable that should be transformed.
times: A numeric indicating the scale factor for IQR. Defaults to 3.
files_level: A string indicating the level of the file. Valid inputs are: 'household', 'h', 'person' or 'p'. If NULL (default), the file level will be retrived from the 'lissy_files' attributes.
variable_level: Level of the variable. Should be either 'household', 'h', 'person' or 'p'. If NULL (default), the function will try to guess the level of the variable. This is done by comparing the value in 'variable' with pre-set lists of variables.
weight: A string with the name of the variable in 'file' that should be used as sample weights.

Value

A list of tibbles with the recoded variable.

Details

If the lissy files passed are at person-level and the variable is household-level, only household heads are used to compute the IQR of the log transformed variable. For person-level variables, all individuals in the file are used.
