Standardize values of an scdf file
This function scales the measured values of an scdf file. It allows for mean centering and standardization based on each single-case data set or a scaling across all cases included in an scdf.
standardize( data, var, center = TRUE, scale = FALSE, m = 0, sd = 1, grand = TRUE )
data |
A single-case data frame. See |
var |
A character string or a vector of character strings with variable names that should be scaled. |
center |
If set TRUE, data are mean centered. |
scale |
If set TRUE, the standard deviation is set. |
m |
The target mean for centering. |
sd |
The target standard deviation for scaling |
grand |
If set TRUE, scaling is based on the mean and standarddeviation of all measurements across all single-cases within the scdf. |
An scdf with the scaled values.

## Standardize a multiple case scdf and compute an hplm ex_sc <- standardize(exampleAB_50, var = "values", center = TRUE, scale = TRUE) hplm(ex_sc)
