Hello, I am a 16 year old student and a beginner to statistics.
I'm lost.
Currently I only have Microsoft Excel 97. And I would like to know the
differences between the following ANOVA tests (in Excel):
ANOVA Single Factor
ANOVA Two-Factors with replication
ANOVA Two-Factors without replication

Any help, hints, direction etc. on this appreciated:
I have a vector of measurements F, and two feature models L and R which
give the pdf of a measurement Fi for that model i.e. P(Fi|Li) and
P(Fi|Ri). Denoting the probability that there is a feature L at position
i in the vector as P(Li) and
If some of your independent (predictor) variables are categorical, then the
dots and zeros are not a problem but merely a refelction of what would be
redundant parameters.

Hello all,
I am trying to fit some data using the NLINFIT of MATLAB and using SAS.
I am trying to fit the well know RICHARDS growth curve.
It looks like y=a*(1-b*exp(-c*t))^d where we want to estimate the
parameters a,b,c,and d. Here t is my input and is age squared while y

1-b*exp(-c*t) is negative only if b*exp(-c*t) 1, which implies
log(b) c*t, I think. Is this a reasonable circumstance in terms of
the theory that led to the Richards growth curve?
You say this occurs frequently in your data; since b and c are
presumably constants for a given data set,

You may want to use the REGRESSION program in Excel (WITH CAUTION).
That way you can create your own models to do what YOU WANT TO DO.
You might want to contact a statistician to help you use REGRESSION
models. You don't need to use some of the Pre-Computer algorithms if
you know who
