適合多個基因/柱的比例模型你好
我想知道是否有辦法製作一個腳本,用於同時返回多個列/基因的風險比和p值。
我的意思是我有一個包含多個列(基因)和多行(患者)的文件。我必須分析100個基因,我將其表達值分類為UP或DOWN調節,我想立即獲得所有這些基因的風險比率,而不必每次在對話框中選擇不同的基因。我使用腳本編輯器,但我無法為我想要的每一列自動執行此功能。
Re: Fit proportional Model for multiple genes/column at onceNo Clue? Even with a script in R?
Re: Fit proportional Model for multiple genes/column at onceHI @Confa ,
Since the genes are responses, you would put all of them into the Y section of Fit Model. You do not have to put them one at a time. Select them all in the Select Columns section can drag and drop them into Y.
Is that what you were looking for?

Re:一次適合多個基因/列的比例模型嗨克里斯,不是真的。
我必須使用Fit Proportiona Hazard模式計算超過150個基因(上調與下調)的風險比(死亡和死亡時間),而不是Fit XY。
這是平台。通常,如果您在框中放入一個“基因”或變量,您將獲得該基因的RR。如果您放置多個基因或變量,您將獲得多變量模型,而不是每個分離變量的單個RR。

Try Stacking all 150 genes. You will have two new columns. Something like Gene Name and Direction. Then use the By field to put the gene name in there and then the direction in teh Model Effects section. You will get a single fit for each gene.
