Weibull function in Excel
I have a survival dataset (see below). I want to fit to Weibull function S(t)=EXP(-alpha*Time^gamma). If I use Excel Solver, alpha=0.00367 and gamma=2.32. If I use a method tranforming probability to Ln(Ln(1/S(t)) which will be a linear function of Ln (t). But I got a different alpha and gamma. When I compared two alphas adn gammas, the Solver results had a better goodness of fit. What is the problem? THanks Month Probability of survival 0 1 1 1 2 0.92 3 0.90 4 0.88 5 0.83 6 0.76 7 0.74 8 0.69 9 0.57 10 0.48 11 0.39 12 0.27 13 0.27 14 0.13

Barbo - > What is the problem? < There is no problem. You should expect a difference. Your Solver method (which I prefer) minimizes sum of squared deviations between actual S and fitted S. The other method uses transformed values, so it does not yield a better fit. (Excel's trendline features use transformations to fit the logarithmic, power, and exponential functions. The approach appears to be a computational convenience. Better fits are obtained using Solver.) - Mike http://www.MikeMiddleton.com Mike@DecisionToolworks.com "Barbo" <Barbo@discussions.microsoft.com> wrote in message news:CFCE454F-D077-4526-BFE5-66902FFE0A12@microsoft.com... > I have a survival dataset (see below).

Hi Mike, thanks for the reply. So if I want to find a function with best fit, adding a trendline is not an proper method. I got the weibull function estimates from someone else and then try to replicate the results in Excel. When I used Solver, most of the time I can get the parameter estimates with the best fit. I was told there is no feasible solution. How to properly use Solver? Thanks Barbo "Mike Middleton" wrote: > Barbo - > > > What is the problem? < > > There is no problem.

How do you stop excel from charting empty cells/null values as zer
I'm trying to create several charts from my excel data. Several of the chart's reference cell (established range) contains formuals. When the cell's formula returns a null value, chart display's as zero. How do I setup chart to display null as nothing versus zero? The workaround for charting calculated cells when you may have missing data is to use an If formula that selects NA() if there is missing data. Something like -- = If( d2 = "", NA(), b2*d2) You'll need to replace your actual cell references and formula. This formula will place a #N/A in tho...

Consistent function of Utilities logon screen when applying hotfix
When our users attempt to install a hotfix roll-up, when they are logging into Dynamic Utilities for the first time, the user interface is very touchy. What I mean is that they must click the username field and then type. Then, they must use the mouse again to click the password field and type. Then, they must click the OK button. If they try to use backspace, enter key, tab key, etc., extra characters are inserted. The only way that they can "edit" their username and password information during logon is to use the mouse to highlight and the type over the information. ...
