calc_quantiles: Calculate Quantiles

In dRiftDM: Estimating (Time-Dependent) Drift Diffusion Models

Calculate Quantiles

Description

Function that calls the underlying quantile calculation functions calc_quantiles_obs() and calc_quantiles_pred(). Does input checks and the data wrangling

Usage

calc_quantiles(
  pdf_u = NULL,
  pdf_l = NULL,
  t_vec = NULL,
  dt = NULL,
  rts_u = NULL,
  rts_l = NULL,
  one_cond,
  probs = NULL,
  b_coding,
  skip_if_contr_low = NULL
)

Arguments

pdf_u, pdf_l	density values for the upper and lower boundary
t_vec	the time space (required for the pdfs)
dt	the step size corresponding to the time space
rts_u, rts_l	vectors of RTs for the upper and lower boundary
one_cond	character label
probs	numeric vector with values between 0 and 1 for the probability levels
b_coding	used for accessing the upper/lower boundary labels, determines the corresponding columns of the returned data.frame (e.g., Quant_corr).
skip_if_contr_low	numeric. If the contribution of the upper or lower PDF to the overall PDF is too low, return NAs for this PDF (see also drift_dm_skip_if_contr_low()).

Details

if pdf_u and pdf_l are not NULL, returns quantiles for the densities

if rts_u and rts_l are not NULL, returns quantiles for the response times

if all are not NULL, returns both.

Value

a data.frame with "Source", "Cond", "Prob"s, "Quant_<u_label>", "Quant_<l_label>" of type c("quantiles", "sum_dist", "stats_dm", "data.frame")
