第一个问题报错为：
    WARNING:  OF THE 5 BOOTSTRAP DRAWS, 3 DRAWS HAD BOTH A SMALLER LRT VALUE THAN THE
     OBSERVED LRT VALUE AND NOT A REPLICATED BEST LOGLIKELIHOOD VALUE FOR THE 2-CLASS MODEL.
     THIS MEANS THAT THE P-VALUE MAY NOT BE TRUSTWORTHY DUE TO LOCAL MAXIMA.
     INCREASE THE NUMBER OF RANDOM STARTS USING THE LRTSTARTS OPTION.
    第二个问题报错为：
         IN THE OPTIMIZATION, ONE OR MORE LOGIT THRESHOLDS APPROACHED AND WERE SET
     AT THE EXTREME VALUES.  EXTREME VALUES ARE -15.000 AND 15.000.
     THE FOLLOWING THRESHOLDS WERE SET AT THESE VALUES:
     * THRESHOLD 1 OF CLASS INDICATOR YJ FOR CLASS 1 AT ITERATION 97

请问您这个问题解决了吗？
