Difference between two numerical variables

Description

Calculating the difference between two numerical variables Listing units with big difference, either the k units with the biggest absolute difference, or units with a absolute difference greater than a threshold Only units with value on both variables are used in the calculations

Usage

Diff2NumVar(
  data,
  idVar,
  xVar,
  yVar,
  strataVar = NULL,
  antall = 5,
  grense = NULL,
  zVar = NULL,
  kommentarVar = NULL
)

Arguments

`data`	Input data set of class data.frame.
`idVar`	Name of an identification variable.
`xVar`	Name of the x variable to be compared.
`yVar`	Name of the y variable to be compared.
`strataVar`	Name of stratification variable. Optional. If strataVar is given, the calculation and listing is performed within each stratum.
`antall`	Parameter specifying how many units with the biggest difference to be listed. Default 5.
`grense`	Parameter specifying a threshold for the units to be listed. This parameter overrules antall. Optional.
`zVar`	Name of the original y variable, before editing. Optional.
`kommentarVar`	Name of a variable giving information about the editing. Optional.

Value

Output of Diff2NumVar is a data set of class data.frame. The variables in the data frame are:

`strata`	The stratum (if strataVar is given, "1" otherwise)
`id`	The input identification variable
`x`	The input x variable
`y`	The input y variable
`Forh`	The ratio between x and y: y / x
`Diff`	The difference between x and y: y - x
`AbsDiff`	The absolute difference: \|Diff\|
`DiffProsAvx`	The difference in percent of x: (Diff / x) * 100
`DiffProsAvSumx`	The difference in percent of the stratum total for x: (Diff / stratum x) * 100
`DiffProsAvTotx`	The difference in percent of the total for x: (Diff / total x) * 100
`SumDiffProsAvSumx`	The stratum difference in percent of the stratum total for x: ((stratum y - stratum x) / stratum x) * 100
`SumDiffProsAvTotx`	The stratum difference in percent of the total for x: ((stratum y - stratum x) / total x) * 100
`z`	The input z variable
`EdEndring`	The difference between z and y: y - z
`Kommentar`	The input kommentar variable
