我一直在尝试使用序数结果运行 proc 逻辑逐步回归模型。因为我试图解释比例赔率的假设，所以我的几个变量的斜率不均匀。因此，在我的代码中，我同时指示了等坡和不等坡，但是我继续收到此语法错误。

ERROR 22-322: Syntax error, expecting one of the following: ;, ABSFCONV, AGGREGATE, ALPHA, BACKWARD, BEST, BINWIDTH, BUILDRULE, CL, 
              CLODDS, CLPARM, CODING, CONVERGE, CORRB, COVB, CT, CTABLE, DETAILS, DSCALE, EXPB, FAST, FCONV, FIRTH, GCONV,

              STOP, STOPRES, TECHNIQUE, UNEQUALSLOPES, WALDCL, WALDRL, XCONV.  
ERROR 76-322: Syntax error, statement will be ignored.

我确信我输入的代码是正确的，即使我没有为 equalslopes 选项和 unequalslopes 选项说明任何特定变量，我仍会继续收到相同的消息。下面是我的代码。

proc logistic data=upper_limit;
class Profitrank dealer_state_id dlr_zip RUCA2 area_description/ param =  ref;
model profitrank =  num_booked num_approved num_apps bk_conversion_rt appr_rt num_new num_used Percentage_of_New Average_Vehicle_Age average_dti

 average_open_rev_trades average_major_derog average_minor_derog average_open_install average_fico_score average_app_risk_score RUCA2) unequalslopes details maxiter=500;
run;``` 

Any help with this would be greatly appreciated!

您需要使用适用于您正在使用的 SAS 版本的选项。在SAS/STAT 14.1中添加了 EQUALSLOPES 选项，这是 2015 年发布的 SAS 9.4m3。

请注意，SAS 是订阅许可证。这意味着您已经支付了使用最新版本的权利。让您公司的人员安装最新版本的 SAS。您可能还需要使用更新版本的企业指南来利用新功能。
