Calculate item level and aggregate learning

Source: R/lca_cor.R

guesstimate

lca_cor(
  transmatrix = NULL,
  nodk_priors = c(0.3, 0.1, 0.1, 0.25),
  dk_priors = c(0.3, 0.15, 0.1, 0.2, 0.05, 0.1, 0.1, 0.25)
)

Arguments

transmatrix

transition matrix returned from multi_transmat

nodk_priors

Optional. Vector of length 4. Priors for the parameters for model that fits data without Don't Knows

dk_priors

Optional. Vector of length 8. Priors for the parameters for model that fits data with Don't Knows

Value

list with two items: parameter estimates and estimates of learning

Examples

# Without DK
pre_test <- data.frame(item1 = c(1, 0, 0, 1, 0), item2 = c(1, NA, 0, 1, 0))
pst_test <- pre_test + cbind(c(0, 1, 1, 0, 0), c(0, 1, 0, 0, 1))
transmatrix <- multi_transmat(pre_test, pst_test)
res <- lca_cor(transmatrix)
