Description Usage Arguments Value Author(s) References Examples

Compares two vectors of lambdas, usually one racial group's support for two separate candidates, or two separate groups' support for the same candidate.

1	lambda_two_compare(lmd, cnames, group_name="Latino", cand1or2=1)

`lmd`	data.frame() object returned from md_bayes_draw_lambda()
`cnames`	Vector of character (column) names, needs to match relevant column names in md_bayes_draw_lambda return.
`group_name`	Character string for name appearing in posterio plot. Default is "Latino")
`cand1or2`	Numeric. Either 1 or 2. Default = 1. Which pairing over the other.

Data frame of the probability of one scenario over the other by 10 pct., by 5 pct., greater than 0 (e.g., what is the probability that candidate 1 beats candidate 2 among Latinos by 10 percentage points, etc.)

  # TOY DATA EXAMPLE
  canda <- c(10,8, 10, 4, 8)
  candb <- 20-canda
  white <- c(15, 12, 18, 6, 10)
  black <- 20 - white
  toy <- data.frame(canda, candb, white, black)
  
  # Generate formula for passage to ei.reg.bayes() function
  form <- formula(cbind(canda,candb) ~ cbind(black, white)) 
  # Then excute md_bayes_draw(); not run here due to time
  # lmd <- md_bayes_draw_lambda(toy, c(2,3), form )

  # cnames <- c("lambda.black.canda", "lambda.black.candb")
