Hello, Is there a simple way to modify the circ.mean function in the CircStats package to include a vector of weights to obtain a weighted average angle? Thanks! Martin -- Martin Biuw Sea Mammal Research Unit Gatty Marine Laboratory, University of St Andrews St Andrews, Fife KY16 8PA Scotland

[R] Confidence prediction limits from bootstrapped linear model

2003-08-15 Thread Martin Biuw
Sorry, I sent this without a subject at first.. Hello, Is there a simple function that calculates standard errors and confidence limits of response values (Y) in a linear model, where parameter estimates have been arrived at by bootstrapping (e.g. according to the first example in Angelo

[R] Comparing two regression slopes

2003-07-30 Thread Martin Biuw
Hello, I've written a simple (although probably overly roundabout) function to test whether two regression slope coefficients from two linear models on independent data sets are significantly different. I'm a bit concerned, because when I test it on simulated data with different sample sizes

[R] Constraining asymptote in SSasymp

2003-07-11 Thread Martin Biuw
Hi all, Is there a simple way to constrain the Asym argument in the SSasymp function so that it does not exceed some maximum value? Thanks! Martin -- Martin Biuw Sea Mammal Research Unit Gatty Marine Laboratory, University of St Andrews St Andrews, Fife KY16 8PA Scotland Ph: +44-(0)1334-462637

Hi, Sorry if this is an obvious one, but is there a simple way to modify the lm function to test whether a slope coefficient is significantly different from 1 instead of different from 0? Thanks, Martin Martin Biuw SEA MAMMAL RESEARCH UNIT Gatty Marine Laboratory School of Environmental
