如何有效地用标签替换多个dummy-coded列? 我试图用实际的分类值替换一些虚拟的编码变量。我知道有很多方法可以用baseR、dplyr和*apply或在函数中替换它,但我的大脑无法在不循环的情况下找出哪种方法最有效。 目前,我有2个数据帧。下面是它们的示例。注意:不是5个变量,而是接近10+的变量,这个操作需要多次执行,所以...

Create dummy coded variablesWilliam Revelle
regression table in that you should be able to calculate the estimates because you are given coefficients. but how can i do this when the dummy variables coded with a “0” have a coefficient and those coded “1” don’t. when i use the equation, won’t this variable always be zero....

In asecond paper in the same journal, the procedure is expanded to regression models that test interaction effects. Within this framework, the weighted effect coded interaction displays the extra effect on top of the main effect found in a model without the interaction effect. This offers a prom...
I dummy coded and have 0's and 1's in my columns but I keep getting the following message- The number of valid active objects is less than 3. This may be due to treating missing data as listwise, or to the specification of supplementary objects, or to weighting objects with zero weigh...
Hello I have a data set with 1800 observations and 7 predictors, first one of which needs to be coded as a dummy variable. The issue is that the variable to be coded as dummy has 73 categories in it. I used dummyvar() function to turn this variable into a 1800 row x 73 column du...
