Hello Sir,
I am trying to solve a problem with Normal Gaussina Error. I have the data in Excel file and the codes in Matlab. In the codes they said that the Normal distribution of the data is generated with error 5% added. How can I find the standard deviation for
the error 10%, 15% and 20%?
this the lines that I have
clear;
t=48;
PV_now= xlsread( 'Data.xlsx','sheet1','C1:C49');
N = 10000;
std1 = 0.063; % 5%
PVreal1=zeros(1,t);
for n=1:N
for j=1:t
PVreal1(j)=PV_now(j)+normrnd(0,PV_now(j)*std1);
end
end
figure
plot(PV_now)
hold on
plot(PVreal1)
and the data are as follows
PV
