Idle Thoughts About Fundamental Improvements A number of "dead ends" have been encountered in the ongoing development of spreadsheets. The "traditional" spreadsheet systems went through a process of "racing for successive refinements" through the late s and early s, largely seeking to add "feature points" to win the contests for "most features counted in the reviews.

The major problem with the "traditional" spreadsheet system is that it does not provide much in the way of "structuring tools" to recognize and enforce the structure of the data model, as described in Problems with Modern Spreadsheet Developments.

Improv proposed better ways of building models, and essentially mandated constructing spreadsheets as a process of constructing a system model. This had the unfortunate, and, as it turns out, unacceptable effect of preventing the "free form" spreadsheet construction that traditional spreadsheets encouraged.

In a traditional spreadsheet, you have a set of rows and columns in which you are free to put anything. It is easy to prototype something up, throwing values here and there wherever it seems convenient to throw them.

In Improv, elements could not be added to the matrix without defining the nature of the row and column. This eliminates "doodling around. On the other hand, if you have to be able to "theoretically" justify every change you make to the shape of the spreadsheet, then the only people that will be using the tool will be "theorists," and to a great extent, that's what happened with Improv.

Model Master provides considerable power in defining models, provides all sorts of "strong typing" options, and provides the logical extension of having the language specify access to robust data sources like relational databases, but has two substantial demerits: It altogether rules out "free form" construction of data into sheets Although this is changing, as construction of a "decompiler" is underway.

It mandates using a declarative programming language to describe the model. The implicit "programmability" of the cellular automata means that the average user doesn't need to know about programming; unfortunately, Model Manager pushes programming in their face.

It seems to me that a "step forward" is to try to take the merits of each of these approaches, whilst seeking to avoid the demerits. It's not a mechanism of infinite analytical power; it likely will only be helpful to find some limited bits of structure.

Of course, "limited" may still be sufficient to actually provide some useful added functionality to relatively unsophisticated users, and forcing people to start from a data modelling perspective, as with Improvhasn't proven terribly popular. Start Out With a Free-Form Sheet The strength of the traditional spreadsheet is in providing a "free form" medium where users may construct models without directly having to program.

So, we start with a front end that is a very "traditional" sort of spreadsheet. Rows, columns, cells, formulae. Attaching "Rules" Via Pattern Wizards It would be nice to get the benefits of Model Master, in providing the ability to attach fairly strong "rules" to portions of the spreadsheet, whether to enforce the use of common formulae or to enforce "strong typing" of the data types used in those regions.

For instance, a region that represents "dates" should contain nothing other than legitimate dates.

The route to this is to use some "artificial intelligence-like" techniques to search for patterns in the data, and to write up rules to propose to the user. I will call these "Pattern Wizards. Detecting sequences of cell contents that look, for instance, like dates.

The proposal would then offer to:AKM Sabbir February 28, at am. it seems its linear time dependent model. is it possible to introduce nonlinearity. what if the transformation is not linear. then how do you approximate the non linearity. every state represents the parametric form of a distribution.

For all but the smallest problems the solution of in each iteration of the Levenberg-Marquardt algorithm is the dominant computational cost in Ceres. Ceres provides a number of different options for srmvision.com are two major classes of methods - factorization and iterative.

A matrix is a rectangular array of numbers written within brackets. The size of a matrix is always given in terms of its number of rows and number of columns (in that order!).

It is more convenient to work not with the system but with its augmented matrix, the array (table, matrix) consisting of the coefficients of the left sides of the equations and the right sides. For example the system (1) from the problem that we just solved has the following augmented matrix.

Augmented matrices. Given the following system of equations, write the associated augmented matrix.

We show how to price the time series and cross section of the term structure of interest rates using a three-step linear regression approach. Our method allows computationally fast estimation of term structure models with a large number of pricing factors.
