Remarkable association signals between the LOTI and solar activity exist on decadal time scales (mainly the 11-year cycle) during 1935-1995, with above the 5 % significance level. Therefore we speculate that there is a stronger link between the LOTI and solar activity that implied by the cross wavelet power.

According to the K-S test theory, when D < [D.sub.crit] (the critical value of [D.sub.crit] for the level of significance [alpha]), the gene has no significant difference between the positive and negative classes when the significance level is [alpha]; if D > [D.sub.crit], there is a significant difference between the positive and negative samples at the 1 - [alpha] confidence level.
