similar to: A function to create "lift charts"

Hi, I have a logit model built in R which I am trying to validate . Could you please help me with creating lift charts and area under ROC for the same. I am trying to use package ROCR The indicative code for this is : newlogit3<- glm(Attrition_ind ~ Time.in.AXP+ Age +as.factor(Increase.in.Rating.in.Current.year) +as.factor(Below.Market.Merit.Budget)+as.factor(Drop.in.AIA)

Dear List, Couple of issues while using functions from ?BCA? library: 1. I am trying to use ?lift.chart? function from ?BCA? library, but facing issues while using model where model formula is passed as formula object in glm. When model formula is written as text, then it works fine. In my case input variables and target variables are going to change dynamically, so have to used formula as

What is the difference between ROC curve and gains/lift chart? how to do them in R? Thanks. -- View this message in context: http://www.nabble.com/ROC-curve-and-gains-lift-chart-tp25083979p25083979.html Sent from the R help mailing list archive at Nabble.com.

Hi all, I'd like to do cross-validation on lm and get the resulting lift curve/table (or, alternatively, the estimates on 100% of my data with which I can get lift). If such a thing doesn't exist, could it be derived using cv.lm, or would we need to start from scratch? Thanks! -- Eric Siegel, Ph.D. President Prediction Impact, Inc.

I also agree with Philippe Grosjean that there is a need to investigate the effects of different types of GUIs on software "usability". To do that, however, there is a need to develop a set of appropriate metrics, and to understand that the appropriateness of a given metric (and ultimately a given type of GUI) is likely to be conditional on the type of user. My sense is that the

Missing are capitalization/formatting of data type & function labels, as well as addressing the unit labels for the y-axis. --- src/flexchart/flexchart.mxml | 4 + src/flexchart/org/ovirt/Constants.as | 17 +++ src/flexchart/org/ovirt/charts/BarChart.as | 155 ++++++++++++++++-------- src/flexchart/org/ovirt/charts/HostChart.as | 42 ++++++-

Hi all, Could anybody give me some pointers to Cross Validation using Lifting Score as error function, as commonly used in data-mining and classification field in marketing and e-commerce research? Thanks!

Hi all, I am using SPC techniques of plotting Xbar, R, S, P and C charts in R.For this I am using qcc package in R and also using the following document for reference. http://www.stat.unipg.it/~luca/Rnews_2004-1-pag11-17.pdf But while plotting S chart, R chartchart and also C chart I am getting following errors. I have plotted the Xbar chart successfully using following command obj <-

I''m making a web site with charts, I''m using "XML/SWF Charts", the problem that I have is that the charts work perfectly when I''m working locally, but when I load all files to the server and I want to see the charts, the browser shows me the next message: This page requires AC_RunActiveContent.js. Does anyone to know the reason and how can I solve?

I have posted some charts for this week, showing critical support and resistance areas, and possible trade setups.. These are for stocks MO, TTEK, IBM, MERQ.. I may post some more before the weekend is over. Check back in future, look for updates as these charts develop. To see the charts, log in here: <http://www.fibmarkets.com/cgi-local/yabb/YaBB.pl> and then click on the "Traders

Have you read the books by Cleveland? His experiments show that most people do better estimating things and comparing things on a linear scale rather than looking at angles and areas (also see http://biostat.mc.vanderbilt.edu/twiki/pub/Main/StatGraphCourse/graphsco urse.pdf) With a dot chart you can set the axis to go from 0 to the total of all groups (see the example I sent before, it could

We regularly get questions about making pie charts, and frequently veer off into the philosophical and practical issues surrounding that form of data graphic: human perception of angles and so on. So while this isn't an R issue, I thought some of you might appreciate this brief discussion of the efficacy of pie charts: http://fakescience.tumblr.com/post/6042293374/understanding-pie-charts

Hi, I tried to stack two charts on top of each other using the following R functions: par(mfrow=c(2,1)) plot(rnorm(1:3),xaxt="n",xlab="") plot(rnorm(1:3)) This created two charts, one on top of the other, but there is too much space between them. Does anyone know how to elimiate the space in between the charts? Thanks, -- Tom [[alternative HTML version deleted]]

I''m facing a problen while developing an app in rails... How can I generate PDF files and Charts....

A very common chart in the financial markets is a split chart with two time series shown in two vertically stacked sub-charts. A classic case would be the top panel showing the time series of historical prices of some stock, and the bottom panel showing the volume traded per day immediately below it. The common x-axis is the dates of the time period covered. I would like to create such a standard

I am exploring neural networks (adding non-linearities) to see if I can get more predictive power than a linear regression model I built. I am using the function nnet and following the example of Venables and Ripley, in Modern Applied Statistics with S, on pages 246 to 249. I have standardized variables (z-scores) such as assets, age and tenure. I have other variables that are binary (0 or 1). In

Hello, I am dealing with data stored in a database as a 'time' object. I export the data from the database to a text file and utilize the 'time_to_sec()' function of the database to convert the human readable time (HH:MM:SS) to seconds so that I can use R to do analysis and create charts of the data. I do not need or use days or dates in the data, and the data range is from
