Statistics subsystem does not like certain numbers in Y. For example,

350.33050223 ENTERAttempt to calculate s (standard deviation) gives domain error.

3.265 [+/-] [EEX] 10 [+/-]

[+]

Cl[SIGMA]

1 [SIGMA]+

2 [SIGMA]+

3 [SIGMA]+

4 [SIGMA]+

5 [SIGMA]+

[g] [5]

This time, the effect is reproducible on emulator.

This is highly number-specific. Many numbers are breaking it, but many numbers pass through. Without that -3.265E-10 it does not give error.
