I probably found a bug in normTable function. If confidence intervals are requested, the interval for percentile works, but it is definitely wrong for the standard score as it shows the upper bound in both columns. An example (using N(10,3)):
In addition, I really like you use regression method. However, I would like to know more about the exact method which is used. Is it SE for observed score, SE = SD*sqrt(1-r)
, or SE for true-score estimate, SE_t = SD*sqrt(r)*sqrt(1-r)
? And the regression was estimated like E(t) = r*X+(1-r)*M
? It would be helpful to provide formula or reference any source with them.
Should be 3.0 instead of 3.0.0. This doesn't matter on CRAN, because in R package_version("3.0") == package_version("3.0.0"), but I found it causes issues in other systems (e.g., RPM packaging).
When using the function bestModel, the predictors I specified started causing error of this type:
Error in (!is.null(predictors)) && (!inherits(predictors, "formula")) && :
'length = 5' in coercion to 'logical(1)'
This happens also in scripts that were fully functioning between 1 and 2 years ago. I am not sure whether I miss something or whether there is some more general error causing this issue?
This is example of my code leading to this issue:
norms_bvmt_model <- bestModel(norms_powers, raw = "score_total", predictors = c("L1", "L3", "L1A3", "A2", "A3"), plot = T, terms = 3)
OS: Linux Mint 19.2; R version 3.4.4
** preparing package for lazy loading

cnorm.cv is broken in R 4.3.0, other functions are evaluated

I am trying to use the shiny app for cNORM but when I open my dataset, I cannot get past preparation as I get the error: Error:argument is of length zero
