predictRaw function

Predict raw values

Most elementary function to predict raw score based on Location (L, T score), Age (grouping variable) and the coefficients from a regression model.

predictRaw(norm, age, coefficients, minRaw = -Inf, maxRaw = Inf)

Arguments

• norm: The norm score, e. g. a specific T score or a vector of scores
• age: The age value or a vector of scores
• coefficients: The a cnorm object or the coefficients from the regression model
• minRaw: Minimum score for the results; can be used for clipping unrealistic outcomes, usually set to the lower bound of the range of values of the test (default: 0)
• maxRaw: Maximum score for the results; can be used for clipping unrealistic outcomes usually set to the upper bound of the range of values of the test

Returns

the predicted raw score or a data.frame of scores in case, lists of norm scores or age is used

Examples

# Prediction of single scores
model <- cnorm(raw = elfe$raw, group = elfe$group)
predictRaw(35, 3.5, model)
