sim.compare.jury.stats: Estimates jury-level differences based on juror-level statistics using simulations based on empirical data

Description

Calculates jury-level differences based on juror-level statistics supplied by user. Results based on empirical data, inferential statistics produced via simulations.

Usage

sim.compare.jury.stats(
  pg_actual,
  n_actual,
  pg_hypo,
  n_hypo,
  jury_n = 12,
  digits = 3,
  pstrikes = 0,
  dstrikes = 0,
  accuracy = 0.15,
  seed = 12345,
  nDraws = 10000
)

Value

Returns a list of jury-level statistics to assess effect of a trial error.

Arguments

pg_actual

The proportion of jurors who favor a guilty verdict in the actual trial condition (the trial with error).

n_actual

The size of the sample used to estimate pg_actual.

pg_hypo

The proportion of jurors who favor a guilty verdict in the hypothetical trial condition (the fair trial without error).

n_hypo

The size of the sample used to estimate pg_hypo.

jury_n

Size of the jury (i.e. 6, 8, or 12); default value is 12.

digits

Number of digits to report after decimal places; default value is 3.

pstrikes

Number of peremptory strikes by prosecution; default value is 0.

dstrikes

Number of peremptory strikes by defendant; default value is 0.

accuracy

Accuracy of parties' peremptory strikes; a number between 0 and 1; default value is .15.

seed

Set seed for random number generation for replication, default is 12345.

nDraws

The number of simulations used to generate results. Should be very large number (default = 10000).

Examples

   library(sate)
   sim.compare.jury.stats(pg_actual=.70, n_actual=400, pg_hypo=.60, n_hypo=450, nDraws=500)

   sim.compare.jury.stats(pg_actual=.75, n_actual=450, pg_hypo=.65, n_hypo=350,
                      seed=12345, nDraws=1000)
