Random Variable Generation
...add them together. However, when I attempt to assign this code to a variable, any time I use the variable, it will always give me the same numbers instead of being random every time. Is there a way I can do this so that it is random every time? Here is the code I am currently using: .35*(runif(1, min=.81, max=1.03)+runif(1, min=1.06, max=1.17)+runif(1, min=-.26, max=1.38))+.3*(runif(1, min=.36, max=.98)+runif(1, min=.76, max=.93)+runif(1, min=.52, max=1.03))+.2*(runif(1, min=.36, max=.75)+runif(1, min=.1, max=.67)+runif(1, min=.9, max=.96))+.15*(runif(1, min=.03, max=.2)+runif(1, min=.27, max=....

Help with the Error Message in R "Error in 1:nchid : result would be too long a vector"
Hello everyone, I am using *mlogit* to analyse my choice experiment data. I have *3 alternatives* for each individual and for each individual I have *9 questions*. I have a response from *516 individuals*. So it is a panel of 9*516 observations. I have arranged the data in long format (it contains 100 columns indicating different variables and identifiers). In mlogit I tried the following

lm( ) for log10-transformed data
Dear help-list, I would like to perform a linear regression on the log10 of the two vectors ov.mag.min and res.600nm. The slope and intercept of the regression I use to plot a wider range of ov.mag.min in a double log plot. For a linear regression on only tow points, wouldn't I expect the results for two.points.min to match pretty exactly res.600nm? It does not seem to be the case here. I ma...

Step command failing for lm function
Hi, I have a fairly simple linear regression using the lm function. There are about 100 variables and 30,000 rows of data. It runs fine and produces a decent looking R2 value. I'm interested in performing a stepwise variable selection to see if things can be cleaned up a bit. Calling the step function returns ONE iteration (all the variables) and then stops. No errors are reported. Can someone suggest why this might not be working as expected. (Normally this function steps through all the va...
