Computer crashes/restarts when running stepwiseglm

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.

thanks, I ran the diagnostic tool. No memory errors were detected

Hello,

thanks for the input, any pointers on how to do that or what to look for?
