我正在使用 R (test.bic.surv) 中的 BMA 包从大量变量（100 个基本变量和每个变量大约 60 个滞后）中估计 Cox 比例模型。当我尝试使用以下代码进行第一组测试时，它可以工作。
x1<- x[,c( "comprisk", "compriskL1", "compriskL2", "compriskL3", "compriskL4", "econrisk", "econrisk_1", "econrisk_2", "econrisk_3", "econrisk_4", "econrisk_5", "finrisk", "finrisk_1", "finrisk_2", "finrisk_3", "finrisk_4", "finrisk_5", "polrisk", "polrisk_1","polrisk_2","polrisk_3","polrisk_4","polrisk_5","polrisk_6","polrisk_7","polrisk_8","polrisk_9","polrisk_10","polrisk_11","polrisk_12")]
surv.t<- x$crisis1
cens<- x$cen1
test.bic.surv<- bic.surv(x1, surv.t, cens, factor.type=FALSE, strict=FALSE, nbest=2000)
但是，每当我尝试将更多自变量添加到 x1 中时，例如“comprisk5L”或“econriskL1”，
test.bic.surv<- bic.surv(x1, surv.t, cens, factor.type=FALSE, strict=FALSE, nbest=2000)
向我展示了这样的错误：
"Error in terms.formula(formula, special, data = data) : '.' in formula and no 'data' argument".
我在网上搜索了几天，但无法弄清楚问题出在哪里。谁能告诉我该怎么做？？提前非常感谢你！！！：）
示例数据如下所示：
