sim.as.jury.stats: Estimates jury-level probability of guilty verdict based on juror-level statistics based on empirical data

Description

Returns estimate of the probability of guilty verdict based on juror-level statistics supplied by user. Also reports inferential statistics. Results are based on an empirical model with greater uncertainty than as.jury.stats function.

Usage

sim.as.jury.stats(
  sample_pg,
  sample_n,
  jury_n = 12,
  pstrikes = 0,
  dstrikes = 0,
  accuracy = 0.15,
  digits = 3,
  nDraws = 10000,
  seed = 12345
)

Value

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

Arguments

sample_pg

The proportion of jurors who favor a guilty verdict in the jury pool

sample_n

The size of the sample used to estimate sample_pg

jury_n

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

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.

digits

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

nDraws

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

seed

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

Examples
