對(duì)此窗口中的數(shù)據(jù)執(zhí)行參數(shù)擬合（請(qǐng)參見第35頁的“直接參數(shù)化模型辨識(shí)”）。需要注意的是赂摆，通過前一個(gè)選項(xiàng)卡上的FIR擬合對(duì)數(shù)據(jù)的參數(shù)擬合給出良好的初始估計(jì)是非常重要的千扔。
Parametric Fit（參數(shù)擬合）窗口布局類似于Pre-Fit（預(yù)擬合）下的Parameters（參數(shù)）子選項(xiàng)卡憎妙。此選項(xiàng)卡有兩種顯示模式：
?Setup Mode（設(shè)置模式）：單元格可更改，不會(huì)變灰曲楚。在此模式下厘唾，你可以執(zhí)行參數(shù)擬合。Low和High值對(duì)應(yīng)于適用于擬合的低限和高限龙誊。此模式中的參數(shù)值可用作初始猜測(cè)抚垃。
?Results Mode（結(jié)果模式）：所有單元格都顯示擬合的不能更改的結(jié)果。此模式顯示了從AIDAPro引擎獲得的結(jié)果趟大。 95％Low和95％High值對(duì)應(yīng)于參數(shù)計(jì)算的95％置信帶鹤树。

FIR Fit Parameters Subtab Fields and Buttons
Redo Fit: Redo the FIR setup and fitting.
Initialize Parametric: Use these parametric approximations as initial inputs for the parametric fit. The results and constraints are copied to the Parametric Fit tab window.
Row Headings: Inputs and intermediates.
Column Headings: Outputs.
**Ramp: **Confirms the output is a ramp.
Contents of each cell
**Model Type: **The list box displays the current type of model selected on the FIR Fit Plots subtab.
**Model Parameters and Constraints: **The number of parameters displayed depends on the set model type. Parameter values and the high and low limits are shown in each cell. The Fit Stat corresponding to that input-output pair is shown in the bottom row of each cell table.
Some of the other options available in this window:
Parameter Constraints: Place constraints on parameters by changing the appropriate low and high limit values. The FIR to PAR model will immediately be updated with these new limits enforced on the F2P model.
Parametric Fit
You perform parametric fit on the data in this window (refer to “Direct Parametric Model Identification” on page 35). It is important that a good initial estimate be given to a parametric fit of data by making a FIR Fit on the previous tab.
The Parametric Fit window layout is similar to the Parameters subtab under Pre-Fit. There are two modes of display for this tab:
**?Setup Mode: **The cells are available for changes and are not grayed out. In this mode you can perform a parametric fit. The Low and High values correspond to low and high limits applicable to the fit. The parameter value in this mode can serve as the initial guess.
**?Results Mode: **All cells display the results of the fit but none can be changed.This mode displays after results are obtained from the AIDAPro engine. The 95% Low and 95% High values correspond to the computed 95 percent confidence bands on the parameters.
Parametric Fit Window Fields
**Fit/New Fit: **? Perform a fit if the window is in setup mode(cells are not grayed out).
? Perform a new fit by changing the current mode from results mode to setup mode.
**Row Headings: **Inputs and Intermediates.
Column Headings: Outputs.
Ramp: Confirms the output is a ramp.
**Contents of each cell: **All the cells have two display modes – Setup and Results modes.
