Suppose that we have two databases :
Database_1 has 300 samples and
Database_2 has 700 samples.
Database_all is combination of two databases.
Is finding outliers using
Database_allis equal to finding outliers separately in
Database_2? In both cases we will remove same samples or not?
Suppose that we will remove outliers with column 1 on above databases. In column
3we have data that we want create a label for every sample like this
mean(column_2)is average of all values in column
2) We want calculate this label for all samples after removing outliers. In this case we have same label values if we remove outliers from
Database_allcompare to calculate after removing outliers separately in
Please mathematically prove this problem if you have time.
