Calculates the mean and standard deviation of all numeric variables in a dataframe or tibble.
Details
The parameter table is used in the computation of Z-values during the standardisation of out-of-sample predictions with pred_to_Zr(). make_param_table() returns a tidy, long-form tibble with the variable names of analysis_data stored in columnvariable, the corresponding parameter ("mean" or "sd"), and the value of that parameter.
Note
Currently variable names of analysis_data must not contain . because this character is used to split the variable from the parameter during pivot_longer()

The table from this function is used to standardize out-of-sample predictions $y_i$ in pred_to_Z()
