Point factor analysis (PFA) is a systemic bureaucratic method for determining a relative score for a job. [1] Jobs can then be banded into grades, and the grades used to determine pay. [2] PFA is a type of job evaluation; the main advantage of PFA is that it is systemic and analytical. Jobs are broken down into factors such as “knowledge ...
The factor model must then be rotated for analysis. [4] Canonical factor analysis, also called Rao's canonical factoring, is a different method of computing the same model as PCA, which uses the principal axis method. Canonical factor analysis seeks factors that have the highest canonical correlation with the observed variables.
Performance rating factor: The number pace the person is working at. 90% is working slower than normal, 110% is working faster than normal, 100% is normal. This factor is calculated by an experienced worker who is trained to observe and determine the rating. Personal, fatigue, and delay (PFD) allowance.
Exploratory Factor Analysis Model. In multivariate statistics, exploratory factor analysis (EFA) is a statistical method used to uncover the underlying structure of a relatively large set of variables. EFA is a technique within factor analysis whose overarching goal is to identify the underlying relationships between measured variables. [1]
Within statistical factor analysis, the factor regression model, [1] or hybrid factor model, [2] is a special multivariate model with the following form:
In confirmatory factor analysis, the researcher first develops a hypothesis about what factors they believe are underlying the measures used (e.g., "Depression" being the factor underlying the Beck Depression Inventory and the Hamilton Rating Scale for Depression) and may impose constraints on the model based on these a priori hypotheses. By ...
This leads to a basic minute value (observed time/100*rating). This balances out fast and slow workers to get to a standard/average time. Standard at a 100 is not a percentage, it simply makes the calculations easier. Most companies that set targets using work study methods will set it at a level of around 85, not 100.
A factor identifier (from Yates' order). The specific identifier will vary depending on the program used to generate the Yates analysis. Dataplot, for example, uses the following for a 3-factor model. 1 = factor 1 2 = factor 2 3 = factor 3 12 = interaction of factor 1 and factor 2 13 = interaction of factor 1 and factor 3
