BA II Plus - Error 4

i was attempting to go through some quant examples with my calculator and got an error 4 message on my BA II Plus calculator. the example was from stalla SS3 page 8 (covariance coefficient). can anyone please advise why this is happening? i’ve re-input the data just to make sure that wasn’t the cause, but i still have the same error. i’ve asked the question to stalla, but i’m still waiting for a response.

lol you asked Stalla. Send a message to Texas Instruments too!

what was the example details… can you paste what stalla asked you to do… so folks who have calculator can help! (I am on Level III - but would be glad to take a look)

I just googled “BA II Plus - Error 4” and looked in their manual. On pages 80-82 of that manual they have the error code descriptions. Error 4 means “Out of Range”. Specifically, they haven’t mentioned what it means when you’re doing covariance coefficient calculations. i too, would be interested in details.

the example was based on this table: Year Return on Zeta Shares (Y) Return on S&P 500 Index (X) 1 10 5 2 -15 -10 3 15 10 4 5 0 5 -5 -10 you have to input these values using the 2nd Data and then get the correlation coefficient (sorry i had put covariance up top, but i meant correlation) by using 2nd Stat. when i get to the 2nd Stat part, i get the Error 4 message.

I had no problem doing this on my calc. I got all values for 2ND-STAT. Reset your calculator by using 2ND-RESET and then try it again.

thank you, iginla2010. after resetting my calculator my problem was fixed. the issue was that when i did 2nd-Stat, the mode i was in was 1-V. this should be LIN (solved by doing 2nd-Set repeatedly until LIN shows up - while in the 2nd-Stat area). also, the number of decimal places was an issue as well. this can be changed by pressing 2nd-Format-the number of decimals you want to show-Enter-2nd-Quit.

Preferably, set your number of decimals to 9, this is the floating setting which will always show you the number of decimals you actually need to see (say 1/2 = 0.5, 1/4 = 0.25, 1/8 = 0.125, 1/16 = 0.0625; no redundant zeros).
