Question about Texas Instruments TI-89 Calculator
I needed to find logistic regression using table of given values, but the calculator is still giving me"singular matrix" in response. What does it mean and what should be done to solve the problem?
I had this problem as well...Were you working on a SinReg equation by any chance? I was able to do every other type of regression (Linear, quadratic, cubic, ect..) In order to get Sinusoidal regression you need to make sure you arrow down to the Period box when entering the equation, and fill it in with the number of items in your table of values (a ten item list means a period of 10). That was the fix for me, so hopefully it works for you!
