Classify Estimate Reliability and Apply Confidentiality Masking

Source: R/fso_mask_flag.R
fso_flag_mask.Rd

fso_flag_mask applies Swiss Federal Statistical Office (FSO) reliability rules for survey estimates, based on the number of observations (occ). It flags low reliability estimates and masks them when sample size is too small (occ <= 4).

Usage

fso_flag_mask(data, lang = c("de", "fr", "it", "en"))

Arguments

data

A data frame or tibble.

lang

A character string for the language of the estimate reliability description, one of "de", "fr", "it", "en". Defaults to German if omitted.

Value

A tibble containing the original data with masked estimates when occ <= 4 and one additional column:

obs_status

character column classifying reliability of estimates.

Details

FSO estimate reliability criteria:

occ <= 4:

No estimate (confidential).

occ <= 49:

Estimate of low reliability.

occ > 49:

Reliable estimate.

Examples

df <- data.frame(occ = c(3, 10, 60), mean_income = c(4000, 4200, 4500))
fso_flag_mask(df)
#>   occ mean_income                     obs_status
#> 1  NA          NA  Kein Schätzwert (vertraulich)
#> 2  10        4200 Schätzwert bedingt verlässlich
#> 3  60        4500         Schätzwert verlässlich
