Computer crashes/restarts when running stepwiseglm
显示 更早的评论
Hello,
I'm running a simple script that runs a GLM using stepwiseglm. I've tried to run the code 6 times now and each time my computer unexpectedly crashed/restarted on its own. Sometimes it crashes soon after I run the script (minutes), sometimes it runs for hours and stepwiseglm produces output (list of components that it included in the model), but it never seems to finish.
Has anyone run into something like this?
My system:
MATLAB 2018b
Win 10 pro
10.0.17134 build 17134
Thanks for any insights!
Script code:
------------------------------------------
%load data
load('B01_POS_NEG.mat')
ResponseVar = B01_POS_NEG{:,10};
PredictorsVar = B01_POS_NEG{:,11:138};
%compute Generalized Linear Model
size = length(PredictorsVar);
%1. stepwise
IncludeP = 0.01; %maximum p-value allowed for included components
ExcludeP = 0.05; %minimum p-value to exclude component
mdl = stepwiseglm(PredictorsVar,ResponseVar,'linear','Distribution','binomial','Link','logit','PEnter',IncludeP,'PEnter',ExcludeP);
%Select linear predictors
scores = mdl.Fitted.LinearPredictor;
------------------------------------------
The B01_POS_NEG variable has 14815 rows and 138 columns, about 15Mb.

I recommend that you check for a hardware memory problem.
