| I have found the following way: #["BestFitParameters"] & /@ # & /@ ols But I still can't make it work with ***Through*.** Cheers |
| The answer provided by ***rhermans*** at StackExchange was perfect! Module[ { names = {"GS", "MS", "BAC"}, dates = {{2000, 1, 1}, {2000, 1, 20}}, filename = "spreadsheet.xls", data }, data =... |
| I have a nested list of financial data such as: test={{{2000,1,4},-5.93336},{{2000,1,5},1.09736},{{2000,1,6},7.19}} I would like to replace `[[All,2]]` with Log[1+[[All,2]]/100] using *ReplacePart* instead of *part assignment*,... |
| I am trying to read .dta with RLink as suggested by Seth but Mathematica doesn't seem to acknowledge the package I want to use. I want to use the *read.dta13* from the *readstata13* package. Needs["RLink`"]; InstallR["RHomeLocation"... |
| I am trying to reproduce the illustration of cleaning up imported data in *Mathematica* from [here][1]. I had to make a slight change in ***input 13*** to `j[x_] := If[StringMatchQ[x, "TOTAL*"], x, DateList[x]];` After running ***input 14***, I... |
| I am running a Monte Carlo simulation to compare errors from least squares method and quantile regression. I have generated the data as per below *(y = x Beta + error)*, for three different beta's. (\\[Tau] is my quantile level) The data is... |
| I contacted the author of this package (Anton Antonov) and not only did he reply in very short notice, he was kind to offer a solution, to which I post the code below. If you are interested in learning how the *QuantileRegressionFit* function works,... |
