S*******u 发帖数: 727 | 1 我想请教一个问题:
我在做LOGISTIC PREDICTION. 我有CONTINOUS 的 INDEPENDENT PREDICTOR,我要TEST
这个CONTINUOUS PREDICTOR 是否与BINARY OUTCOME 有RELATED.但是我不想把
CONTINUOUS 的VARAIBLE 变成CATEGORICAL,用哪个TEST 测CONTINUOUS VARIABLE 与
BINARY OUTCOME 的相关性?
谢谢了 | w**********n 发帖数: 36 | 2 难道不是用这个连续变量作为PREDICTOR, 然后TEST COEFFICIENT是否SIGNIFICANT? | l**********8 发帖数: 305 | 3 for ordinal or continuous variables, may also determine if the
ln(odds) seems to be linearly related or not. Plot the logit of the group
means
vs the midpoint of the group. Will give an idea of whether to model as
linear, quadratic, or possibly just categorical | l**********8 发帖数: 305 | 4 可以看这个variable的Wald‘s test的p value | S*******u 发帖数: 727 | 5 是这样的.
Object: Test whether age is related to the binary outcome(Coupon RedemptionY
/N)?
就是TEST 是否使用COUPON 是否与AGE 有关.
我不想把AGE 变成AGE GROUP( 18-28, 28-38, 39-49....),如果变成AGE GROUP, 我可
用CHI-SQUARE TEST.
但是我想用AGE 是 CONTINUOUS 的.比如(20,12, 22, 23.....60..)但是不知道该用哪
个TEST THE RELATED OR NOT RELATED?
【在 w**********n 的大作中提到】 : 难道不是用这个连续变量作为PREDICTOR, 然后TEST COEFFICIENT是否SIGNIFICANT?
| l**********8 发帖数: 305 | 6 Just do logistic procedure , then look at wald' s test result from output , |
