Write a C program to find the statistical error like Mean Error, Percentage error, Mean percentage error and Absolute percentage error.

• Mean error
• Percentage error
• Mean Percentage error
• Absolute Percentage error

C Code to find statistical error

#include<stdio.h>
#include<stdlib.h>
void main()
{
 int n,i;
 float sum=0,a[100],b[100],me=0,pe=0,mpe=0,ampe=0,s=0;
 printf("\nHOW MUCH FIND NO. OF MEAN PLEASE ENTER=>");
 scanf("%d",&n);
 printf("\nEnter the element number=>");
 for(i=0;i<n;i++)
 {
  scanf("\n%f",&a[i]);
 }
for(i=0;i<n;i++)
 {
  printf("\n%f",a[i]);
 }
printf("\n");
printf("\nEnter the element number=>");
  for(i=0;i<n;i++)
 {
  scanf("\n%f",&b[i]);
 }
for(i=0;i<n;i++)
 {
  printf("\n%f",b[i]);
 }

for(i=0;i<n;i++)
 {
  sum=sum+(a[i]-b[i]);
 }
for(i=0;i<n;i++)
{
 me=me+(sum/n);
}
printf("\nThe Mean error=>%f\n",me);
pe=(pe+me)*100;
printf("\nThe mean Percentage error=>%f\n",pe);
mpe=(mpe+pe)/n;
printf("\nThe Mean Percentage error=>%f\n",mpe);
ampe=ampe+abs(mpe);
printf("\nThe Mean Absolute Percentage error=>%f\n",ampe);
for(i=0;i<n;i++)
{
s=(s+abs(mpe))/n-1;
}
printf("\nThe navie freqeucy=>%f\n",s);
}
