vpcstats function

Compute VPC statistics

Compute VPC statistics

Compute prediction interval statistics for VPC.

vpcstats(o, ...) ## S3 method for class 'tidyvpcobj' vpcstats( o, vpc.type = c("continuous", "categorical"), qpred = c(0.05, 0.5, 0.95), ..., conf.level = 0.95, quantile.type = 7 )

Arguments

  • o: A tidyvpcobj.
  • ...: Other arguments to include.
  • vpc.type: Character specifying type of VPC (e.g., "continuous" (Default) or "categorical").
  • qpred: Numeric vector of length 3 specifying quantile prediction interval. Only applicable for vpc.type = "continuous".
  • conf.level: Numeric specifying confidence level.
  • quantile.type: Numeric indicating quantile type. See quantile.

Returns

Updates tidyvpcobj with stats data.table object, which contains the following columns:

  • bin: Resulting bin value as specified in binning() function
  • xbin: Midpoint x-value of the observed data points in the bin as specified in xbin argument of binning() function
  • qname: Quantiles specified in qpred. Only returned if vpc.type = "continuous"
  • pname: Categorical probability names. Only returned if vpc.type = "categorical"
  • y: Observed y value for the specified quantile
  • lo: Lower bound of specified confidence interval for y value in simulated data
  • md: Median y value in simulated data
  • hi: Upper bound of specified confidence interval for y value in simulated data
