Consistency tests

Check the numerical consistency of summary statistics; three tests currently implemented —

GRIM

Test reported means or percentages for numerical consistency with reported sample sizes

grim(): The GRIM test (granularity-related inconsistency of means)

grim_map(): GRIM-test many cases at once

grim_map_seq(): GRIM-testing with dispersed inputs

grim_map_total_n(): GRIM-testing with hypothetical group sizes

grim_plot(): Visualize GRIM test results

grim_probability() grim_ratio() grim_total(): Possible GRIM inconsistencies

grim_granularity() grim_items(): Granularity of non-continuous scales

GRIMMER

Test reported means and standard deviations for numerical consistency with reported sample sizes

grimmer(): The GRIMMER test (granularity-related inconsistency of means mapped to error repeats)

grimmer_map(): GRIMMER-test many cases at once

grimmer_map_seq(): GRIMMER-testing with dispersed inputs

grimmer_map_total_n(): GRIMMER-testing with hypothetical group sizes

DEBIT

Test reported means and standard deviations of binary data for numerical consistency with reported sample sizes

debit(): The DEBIT (descriptive binary) test

debit_map(): Apply DEBIT to many cases

debit_map_seq(): Using DEBIT with dispersed inputs

debit_map_total_n(): Use DEBIT with hypothetical group sizes

debit_plot(): Visualize DEBIT results

sd_binary_groups() sd_binary_0_n() sd_binary_1_n() sd_binary_mean_n(): Standard deviation of binary data

Duplicate detection

Blunt functions to tentatively discover and count duplicate numeric values; interpret results with care

duplicate_count(): Count duplicate values

duplicate_count_colpair(): Count duplicate values by column

duplicate_tally(): Count duplicates at each observation

Summarize scrutiny tests

Follow up on scrutiny’s testing functions by computing specific summary statistics

audit(): Summarize scrutiny objects

audit_seq() audit_total_n(): Summarize output of sequence mappers and total-n mappers
