Minitab displays the parameters of the Johnson transformation function that produces the best fit. Minitab uses this function to transform the original data.
For example, suppose the Johnson transformation function is 0.762475 + 0.870902 × Ln((X – 46.3174 ) / (59.6770 – X)). If the original data value for X is 50, then the transformed data value of 50 is calculated as 0.762475 + 0.870902 × Ln((50 – 46.3174) / (59.6770 – 50)), which equals –0.07893.
To store all the transformed data values in the worksheet, enter a storage column when you perform the analysis.
