问题 I want to add at-risk table and 95% confidence intervals to adjusted survival curves. Something like survival curves below (Link). I saw some relevant code here but it doesn't mention what I need. Another question, would it be correct if I used the obtained weight variable (from iptw package) in the adjustment (as I have a column named weight in my actual dataset. Here is my code: library(survival);library(survminer) data(lung);names(lung) #fit <- coxph( Surv(time, status==2) ~ ph.karno +

问题 I have created a textbox in a Windows Forms application that starts out at a height for entering text in a single line. But I would like the textbox to automatically increase its height if the user enters text that is wrapped within the control.

I've tried using the TextChanged event to determine when the text has been wrapped but I'm unable to find any property that will help me with this. The Lines

Adjusting image intensity values

阅读更多关于 Adjusting image intensity values

问题 I came to the imadjust function in MATLAB . It seems that this function enhances the contrast of the image. But, what is the theoretical basis for this function? In other words, if I say that this function as mentioned in the documentation adjusts the image intensity values, what does this exactly mean? What is it doing to the intensity values? Thanks. 回答1: The formula for each pixel is likely to be J = ((((I - low_in) / (high_in - low_in)) ^ gamma) * (high_out - low_out)) + low_out If you

问题 I need a solution for auto-adjusting the width and height of an iframe to barely fit its content. The point is that the width and height can be changed after the iframe has been loaded. I guess I need an event action to deal with the change in dimensions of the body contained in the iframe. 回答1: <script type="application/javascript"> function resizeIFrameToFitContent( iFrame ) { iFrame.width = iFrame.contentWindow.document.body.scrollWidth; iFrame.height = iFrame.contentWindow.document.body
