Why does Main have to find all the parameters for other classes?
If a parameter comes from command line, sure Main needs to process it,
but for everything else, such as configurations, each class/component
should deal with it itself.
If the API chain Main->A->B->C->... is so easy to be penetrated by
any parameter changes, I would first ask myself whether I have got
too many layers in the design, and maybe some of them are not doing
anything but passing through parameters.

I don't see anything terribly wrong in this. If the parameters are constantly
changing, maybe consider a hierarchy of parameter bean classes (as somebody
else suggested earlier), so that you don't have to keep changing method
signatures.
Another alternative would be to make the Rule classes themselves parameter
beans. The Converter would inject parameters into a Rule bean prior to calling
its conversion method, instead of passing them as parameters. If most XML
files are large files, conversio |

Attribute classes can have positional parameters and named parameters. Each
public instance constructor for an attribute class defines a valid sequence
of
positional parameters for that attribute class. Each non-static public
read-write field and property for an attribute class defines a named
parameter
for the attribute class. |

发帖数: 12 | 6 How can I do parameter data fitting?
Say I have three parameter Darcy Friction fator equation:
f = A[1]/Re + A[2]*Re^A[3]
The model parameter to be determine is A[1],A[2],A[3] and the +/- intervals
for confidence level.
Try to get the parameter based on experiment data.
What software can do this?
Thank you |

发帖数: 14569 | 9 Parameter passing between classes always bother me a lot. Noramlly, you take
parameters at Main class, then spread it to controls, then to different
modules/classes. A typical flow is like:
Main -> A -> B -> ... -> Z
Headache part is: At the beginning of design, you think B need param1 and
param2; then Main pass both to A, next B. Later, you find B actually needs
param1 and param3. Now you need to change all parameter passing sequence of
Main -> A, and A -> B. If the chain gets longer, it will b |

事多,给忘了这茬.
我当时的意思是parameters.
如果parameters是object.
这个object有可能会被这个method修改.
所以有此疑问.
如果这个method是sychronized, 它的parameters是不是也默认为synchronized.

I may not be clear about my question, let me rephrase it.
For time series data, state space model, if the parameter is not static,
change over time
X_t = F_t * X_t-1 + R.
Y_t = H_t * X_t
What's the best way for finding the online parameter?
I found resurve Least Sqaure Error/Gaussian Newton method/Kalman filter all
can be used to do the online parameter estimate, what's the best method?
Anyone has experience?

发帖数: 74 | 13 In a multivariate linear regression model, if the observations are
correlated with a known pairwise correlation coefficient,
how would the parameter and standard error estimate deviate from the same
model with independent observations?
If the correlation is very small, are there ways to correct the parameter
and standard error obtained from the model with independent observations to
estimate the parameter and standard error for the model with correlated
observations?
Any help is appreciated! |

Default parameter is still considered as part of the function signature,
correct? Thus in this case, B::Func1() actually is "hiding" A::Func1(),
instead of "overriding". So why A::Func1()'s default parameter will be
used? I'm really confused... |

three separate parts:
1) a spider like class, which goes through a directory.
2) a convertor, which is in charge of reading/wrting xml file,
parse/syntactic analysis xml file.
3) rules.
As i can see, the only parameter necessary to be passed from 1) -> 2) -3)
is pathname/File reference.
