是否有 SAS PROC 语句允许我使用指示变量来创建多元线性回归模型？
Is there a SAS PROC statement that allows me to use indicator variables to create a multiple linear regression model?
我试图找到一个多元线性回归模型，并使用数值数据作为指示变量，将其作为定性数据。例如，如果其中一个变量是 "cars owned" 并且响应是 1、2 或 3，我想使用指示变量。
您可能想看看 CLASS statement in PROC GLM. By placing a variable in CLASS, you instruct SAS to treat it as categorical and convert it into classification variables (that is what you call indicators). To control which level is used as a reference, use ORDER = option in PROC GLM statement (details here)。
