Re: [R-es] como hacer un simple barchart horizontal ordenado por el valor ...

Eric, En un barplot, el orden que se usa es el de los niveles del factor. Al crear un factor, por defecto este orden es alfabético. Lo que tienes que hacer es reordenar los niveles del factor usando el criterio de la otra variable (podría ser cualquier función aplicada a las observaciones del

[R] Output interpretation: standard error of lm dummy variable

Hi guys I have a statistical question to an analyse I ran in R. It is a dummy variable model with the 5 regions of Denmark as 4 independent dummy variables and price as the dependent variable: price = 10.325 - 0.176*Sjaeland - 0.368 * NJylland - 0.230*MJylland - 0.120* Syddanmark I

Re: [R] Output interpretation: standard error of lm dummy variable

Hi Livia, You seem to have mixed up the residual error with the R^2, which is just over 0.02. The bottom line on your summary table says that the obtained F statistic was equal to 1894 (this has been truncated to four significant places). The probability of obtaining that value with your data

[R] Finding Optimum of Stochastic Function

Most of the stochastic optimization methods are directed at multiple optima. You appear to have an imprecisely determined function e.g., time taken for racing driver to get round the track, and indeed this is a different form of stochastic optimization. With Harry Joe of UBC I did quite a bit of

Is this a list of data.frames or what? Please have a look at one or both of these for some ideas of how to ask a question and provide information on the problem. The better you can describe what you have and what you need the better people can help.

Re: [R] Urgent :) Output interpretation: standard error of lm dummy variable

Technically it is not on topic to discuss the statistics behind R calculations here, and certainly not our job to do so within the context of your educational institution's schedule. However, you have the power to read the source code of any function in R or contributed packages, so go for it.
