标题: BA II Plus - Error 4 [打印本页] 作者: bleach 时间: 2011-7-11 19:18 标题: 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.作者: mp3bu 时间: 2011-7-11 19:18
lol you asked Stalla. Send a message to Texas Instruments too!作者: zhaoyp 时间: 2011-7-11 19:18
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.作者: yospaghetti 时间: 2011-7-11 19:18
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.作者: DSquaredSlim 时间: 2011-7-11 19:18
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.作者: eoin 时间: 2011-7-11 19:18
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.
