Estimation of  the Swedish time correction factor LYS  using the formula

LYS3=0.2623*(LÖA^0.2743)*(B^0.0507)*(DEPL^-0.1390)*(SA^0.1878)*(PELP^0.1778)*(SPA^0.0412)

where SA is estimated as SA=(P*E+T*LP)/2,  PELP=P/(E+LP)  and  SPA=SL*SMW.  All units in meters and tons.

This formula estimates LYS for the boats in the table over the Lidingö yardstick from ESYS  (descriptions of the parameters ) which have nonzero values for the parameters LÖA, B, DEPL, P, E, T, LP, SL and SMW and have LYS > 0.80, with an error:

            less than 0.025 for 68% of the boats,
            less than 0.038 for 87% of the boats and
            less than 0.050 for 96% of the boats.
